Ultravist Injection Dosage and Administration

Important Administration Instructions

ULTRAVIST IMAGING BULK PACKAGE is for intravenous use only not for direct infusion.
Visually inspect Ultravist Injection for particulate matter and/or discoloration, whenever solution and container permit. Do not administer Ultravist Injection if particulate matter (including crystals) and/or discoloration is observed or if containers are defective. As Ultravist Injection is a highly concentrated solution, crystallization (milky-cloudy appearance and/or sediment at bottom, or floating crystals) may occur.
Use sterile technique for all handling and administration of ULTRAVIST.
Determine the volume and concentration of Ultravist Injection to be used considering factors such as age, body weight, size of the vessel and the rate of blood flow within the vessel; consider also extent of opacification required, structure(s) or area to be examined, disease processes affecting the patient, and equipment and technique to be employed. Specific dose adjustments for age, gender, weight and renal function have not been studied for Ultravist Injection. As with all iodinated contrast agents, lower doses may have less risk. The efficacy of Ultravist Injection below doses recommended has not been established.
Administer ULTRAVIST at or close to body temperature.

Do not mix or inject Ultravist Injection in intravenous administration lines containing other drugs or total nutritional admixtures. ULTRAVIST can be mixed with saline when used in a power injector suitable for simultaneous injection of contrast and saline [see Dosage and Administration (2.2)].

The maximum recommended total dose of iodine in adults is 86 grams; a maximum recommended total dose of iodine has not been established for pediatric patients.
Hydrate patients, as appropriate, prior to and following the administration of Ultravist Injection [see Warnings and Precautions (5.2)].

Utilize aseptic technique for penetrating the container closure of the ULTRAVIST Imaging Bulk Package and transferring Ultravist Injection. The container closure may be penetrated only one time with a suitable sterile component of the automated contrast injection system, contrast management system, or contrast media transfer set approved or cleared for use with this contrast agent in this this Imaging Bulk Package.
3.
Once the ULTRAVIST Imaging Bulk Package is punctured, do not be remove it from the work area during the entire period of use. Maintain the bottle in an inverted position such that container contents are in continuous contact with the dispensing set.
4.
A maximum use time of 10 hours from initial puncture is permitted to complete fluid transfer. Discard any unused Ultravist Injection 10 hours after initial puncture of the Imaging Bulk Package.
5.
After the container closure is punctured, if the integrity of the Imaging Bulk Package and the delivery system cannot be assured through direct continuous supervision, the Imaging Bulk Package and all associated disposables for the automated contrast injection system, contrast management system, or contrast media transfer set should be discarded.
 
Storage temperature of Imaging Bulk Package after the closure has been entered should not exceed 25°C (77°F) excursions permitted to 15–30°C (59–86°F); however, it is desirable that the contents be warmed to body temperature prior to injection.

Dosage Forms and Strengths

Ultravist Injection is a nonionic, sterile, clear, colorless to slightly yellow, odorless, pyrogen-free aqueous solution of iopromide available as an Imaging Bulk Package in two strengths:

300 mg Iodine per mL provides 623.4 mg/mL iopromide

370 mg Iodine per mL provides 768.86 mg/mL iopromide

Contraindications

Do not administer Ultravist Injection intrathecally. Inadvertent intrathecal administration may cause death, convulsions, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, seizures, rhabdomyolysis, hyperthermia, and brain edema.
Preparatory dehydration (for example, prolonged fasting and the administration of a laxative) before Ultravist Injection is contraindicated in pediatric patients because of risk of acute renal failure.

Warnings and Precautions

Hypersensitivity Reactions

Life-threatening or fatal, hypersensitivity reactions, may occur during or after Ultravist Injection administration. Manifestations include respiratory arrest, laryngospasm, bronchospasm, angioedema, and shock. Increased risk is associated with a history of previous reaction to a contrast agent (3-fold), a known sensitivity to iodine and known allergic disorders (that is, bronchial asthma, hay fever and food allergies) or other hypersensitivities (2-fold).

Monitor all patients for hypersensitivity reactions. Emergency facilities and personnel trained in the treatment of hypersensitivity reactions should be available for at least 30 to 60 minutes after Ultravist Injection administration.

Contrast Induced Acute Kidney Injury

Acute kidney injury, including renal failure, may occur after intravascular administration of Ultravist Injection. Risk factors include: pre-existing renal insufficiency, dehydration, diabetes mellitus, congestive heart failure, advanced vascular disease, elderly age, concomitant use of nephrotoxic or diuretic medications, multiple myeloma / paraproteinemia, repetitive and/or large doses of Ultravist Injection.

Use the lowest necessary dose of Ultravist Injection in patients with renal impairment. Hydrate patients, as appropriate, prior to and following Ultravist Injection administration.

Cardiovascular Reactions

Ultravist Injection increases the circulatory osmotic load and may induce acute or delayed hemodynamic disturbances in patients with congestive heart failure, severely impaired renal function, combined renal and hepatic disease, combined renal and cardiac disease, particularly when repetitive and/or large doses are administered [see Drug Interactions (7)].

Among patients who have had cardiovascular reactions, most deaths occurred from the start of injection to 10 minutes later; the main feature was cardiac arrest with cardiovascular disease as the main underlying factor. Reports of hypotensive collapse and shock have been published.

The administration of Ultravist Injection may cause pulmonary edema in patients with heart failure. Based upon published reports, deaths from the administration of iodinated contrast agents range from 6.6 per 1 million (0.00066 percent) to 1 in 10,000 patients (0.01 percent). Observe patients with preexisting cardiovascular disease for several hours following Ultravist Injection administration.

Thromboembolic Complications

Angiography may be associated with local and distal organ damage, ischemia, thromboembolism and organ failure including stroke, brachial plexus palsy, chest pain, myocardial infarction, sinus arrest, hepato-renal function abnormalities. For these reasons, meticulous angiographic techniques are recommended, including close attention to guide wire and catheter manipulation, use of manifold systems and/or three-way stopcocks, frequent catheter flushing with heparinized saline solutions and minimizing the length of the procedure. In angiographic procedures, consider the possibility of dislodging plaques or damaging or perforating the vessel wall with resultant pseudoaneurysms, hemorrhage at puncture site, dissection of coronary artery during catheter manipulations and contrast agent injection. The physicochemical properties of the contrast agent, the dose and the speed of injection can influence the reactions. Test injections to ensure proper catheter placement are suggested. Increased thrombosis and activation of the complement system has also occurred. Specialized personnel, and adequate equipment and facilities for immediate resuscitation and cardioversion are necessary. Monitor electrocardiograms and vital signs throughout the procedure.
Exercise care when performing venography in patients with suspected thrombosis, phlebitis, severe ischemic disease, local infection, venous thrombosis or a totally obstructed venous system.
Clotting may occur when blood remains in contact with syringes containing iodinated contrast agents.
 
Avoid angiography whenever possible in patients with homocystinuria because of the risk of inducing thrombosis and embolism [see Clinical Pharmacology (12.2)].

Reactions in Patients with Hyperthyroidism, Pheochromocytoma, or Sickle Cell Disease

Thyroid storm in patients with hyperthyroidism. Thyroid storm has occurred after the intravascular use of iodinated contrast agents in patients with hyperthyroidism, or with an autonomously functioning thyroid nodule. Evaluate the risk in such patients before use of any iodinated contrast agent.

Hypertensive crises in patients with pheochromocytoma. Administer iodinated contrast agents with extreme caution in patients with known or suspected pheochromocytoma. Inject the minimum amount of contrast necessary. Assess the blood pressure throughout the procedure, and have measures for treatment of a hypertensive crisis readily available.

Sickle cell disease. Contrast agents may promote sickling in individuals who are homozygous for sickle cell disease when administered intravascularly.

Extravasation

Extravasation of Ultravist Injection may cause tissue necrosis and/or compartment syndrome, particularly in patients with severe arterial or venous disease.

Increased Radiation Exposure

The decision to use contrast enhancement is associated with risk and increased radiation exposure. Use contrast after a careful evaluation of clinical, other radiologic data, and the results of non-contrast CT findings, taking into account the increased radiation dose and other risks.

Interference with Image Interpretation

As with other iodinated contrast agents, the use of Ultravist Injection may obscure some lesions which were seen on non-contrast CT scans. Calcified lesions are less likely to enhance. The enhancement of tumors after therapy may decrease. The opacification of the inferior vermis following contrast agent administration has resulted in false-positive diagnosis. Cerebral infarctions of recent onset may be better visualized with contrast enhancement. However, older infarctions may be obscured by the contrast agent.

In patients with normal blood-brain barriers and renal failure, iodinated contrast agents have been associated with blood-brain barrier disruption and accumulation of contrast in the brain. Accumulation of contrast in the brain also occurs in patients where the blood-brain barrier is known or suspected to be disrupted.

Severe Cutaneous Adverse Reactions

Severe cutaneous adverse reactions (SCAR) may develop from 1 hour to several weeks after intravascular contrast agent administration. These reactions include Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN), acute generalized exanthematous pustulosis (AGEP) and drug reaction with eosinophilia and systemic symptoms (DRESS). Reaction severity may increase and time to onset may decrease with repeat administration of contrast agent; prophylactic medications may not prevent or mitigate severe cutaneous adverse reactions. Avoid administering ULTRAVIST to patients with a history of a severe cutaneous adverse reaction to ULTRAVIST.

Adverse Reactions

The most important adverse drug reactions in patients receiving ULTRAVIST are anaphylactoid shock, contrast induced acute kidney injury, coma, cerebral infarction, stroke, brain edema, convulsion, arrhythmia, cardiac arrest, myocardial ischemia, myocardial infarction, cardiac failure, bradycardia, cyanosis, hypotension, shock, dyspnea, pulmonary edema, respiratory insufficiency and aspiration.

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect or predict the rates observed in practice.

The following table of incidence of reactions is based upon controlled clinical trials in which Ultravist Injection was administered to 1142 patients. This listing includes all reported adverse reactions regardless of attribution.

Adverse reactions are listed by System Organ Class and in decreasing order of occurrence for rates greater than 1% in the Ultravist Injection group: see Table 2.

Postmarketing Experience

The following adverse reactions have been identified during post approval use of Ultravist Injection. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

Adverse reactions reported in foreign postmarketing surveillance and other trials with the use of Ultravist Injection include:

Cardiac disorders: cardiac arrest, ventricular fibrillation, atrial fibrillation,tachycardia, palpitations, congestive heart failure, myocardial infarction, angina pectoris

Ear and labyrinth disorders: vertigo, tinnitus

Endocrine disorders: hyperthyroidism, thyrotoxic crisis, hypothyroidism; Thyroid function tests indicative of hypothyroidism or transient thyroid suppression have been uncommonly reported following iodinated contrast administration to adult and pediatric patients, including infants. Some patients were treated for hypothyroidism.

Eye disorders: mydriasis, lacrimation disorder

Gastrointestinal disorders: dysphagia, swelling of salivary glands

Immune system disorders: anaphylactoid reaction (including fatal cases), respiratory arrest, anaphylactoid shock, angioedema, laryngeal edema, laryngospasm, bronchospasm, hypersensitivity

Musculoskeletal and connective tissue disorders: compartment syndrome in case of extravasation

Nervous system disorders: cerebral ischemia/infarction, paralysis, paresis, transient cortical blindness, aphasia, coma, unconsciousness, amnesia, hypotonia, aggravation of myasthenia gravis symptoms

Renal and urinary disorders: renal failure, hematuria

Respiratory, thoracic and mediastinal disorders: pulmonary edema, acute respiratory distress syndrome, asthma

Skin and subcutaneous tissue disorders: Reactions range from mild (e.g. rash, erythema, pruritus, urticaria and skin discoloration) to severe [e.g. Stevens-Johnson Syndrome and toxic epidermal necrolysis (SJS/TEN), acute generalized exanthematous pustulosis (AGEP) and drug reaction with eosinophilia and systemic symptoms (DRESS)].

Vascular disorders: vasospasm

Pediatrics

The overall character, quality, and severity of adverse reactions in pediatric patients are generally similar to those reported in adult patients. Additional adverse reactions reported in pediatric patients from foreign marketing surveillance or other information are: epistaxis, angioedema, migraine, joint disorder (effusion), muscle cramps, mucous membrane disorder (mucosal swelling), conjunctivitis, hypoxia, fixed eruptions, vertigo, diabetes insipidus, and brain edema [see Use in Specific Populations (8.4)].

Drug Interactions

Drug-Drug Interactions

In patients with renal impairment, biguanides can cause lactic acidosis. Ultravist Injection appears to increase the risk of biguanide induced lactic acidosis, possibly as a result of worsening renal function [see Warnings and Precautions (5.2)].

Patients on beta-blockers may be unresponsive to the usual doses of epinephrine used to treat allergic reactions. Because of the risk of hypersensitivity reactions, use caution when administering iodinated contrast agents to patients taking beta-blockers.

Interleukins are associated with an increased prevalence of delayed hypersensitivity reactions after iodinated contrast agent administration. These reactions include fever, chills, nausea, vomiting, pruritus, rash, diarrhea, hypotension, edema, and oliguria.

Renal toxicity has been reported in a few patients with liver dysfunction who were given an oral cholecystographic agent followed by intravascular contrast agents. Administration of any intravascular contrast agent should therefore be postponed in patients who have recently received a cholecystographic contrast agent.

Do not mix other drugs with Ultravist Injection except saline [see How Supplied/Storage and Handling (16)].

Drug-Laboratory Test Interactions

Thyroid Function Tests:

The results of protein bound iodine and radioactive iodine uptake studies, which depend on iodine estimation, will not accurately reflect thyroid function for at least 16 days following administration of iodinated contrast agents. However, thyroid function tests which do not depend on iodine estimations, for example, T3 resin uptake and total or free thyroxine (T4) assays are not affected.

Laboratory Assay of Coagulation Parameters, Fibrinolysis and Complement System:

The effect of iopromide on coagulation factors in in vitro assays increased with the administered dose. Coagulation, fibrinolysis and complement activation were evaluated with standard citrated human plasma in the following assays: thrombin time, thrombin coagulase time, calcium thromboplastin time, partial thromboplastin time, plasminogen, thrombin, alpha-2 antiplasmin and factor XIIa activity. Thrombin inhibition was almost complete. Data on reversibility are not available. The thrombin time increased from approximately 20 seconds at an iopromide concentration of 10 mg Iodine per mL, up to 100 seconds at an iopromide concentration of 70 mg Iodine per mL.

The PTT increased from approximately 50 seconds at an iopromide concentration of 10 mg Iodine per mL, up to approximately 100 seconds at an iopromide concentration of 70 mg Iodine per mL. A similar increase was noted in the thrombin coagulase time. Lesser effects were noted in the calcium thromboplastin time. Coagulation time increased from 13.5 to 23 seconds at the highest iopromide concentration of 70 mg Iodine per mL. The Hageman factor split products decreased by about 20% over the range of 10 to 70 mg Iodine per mL of iopromide. Plasminogen was relatively stable. There was no evidence of activation of fibrinolysis. The complement alternate pathway was activated. Factor B conversion increased in a dose dependent manner. The duration of these effects was not studied.

In vitro studies with human blood showed that iopromide had a slight effect on coagulation and fibrinolysis. No Factor XIIa formation could be demonstrated. The complement alternate pathway also can be activated.

USE IN SPECIFIC POPULATIONS

Pregnancy

Pregnancy Category B

Reproduction studies performed with iopromide in rats and rabbits at doses up to 3.7 g I/kg (2.2 times the maximum recommended dose for a 50 kg human, or approximately 0.7 times the human dose following normalization of the data to body surface area estimates) have revealed no evidence of direct harm to the fetus. Embryolethality was observed in rabbits that received 3.7 g I/kg, but this was considered to have been secondary to maternal toxicity. Adequate and well-controlled studies in pregnant women have not been conducted. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.

Nursing Mothers

It is not known whether Ultravist Injection is excreted in human milk. However, many injectable contrast agents are excreted unchanged in human milk. Although it has not been established that serious adverse reactions occur in nursing infants, caution should be exercised when intravascular contrast agents are administered to nursing women because of potential adverse reaction, and consideration should be given to temporarily discontinuing nursing.

Pediatric Use

The safety and efficacy of Ultravist Injection 300 mg iodine per mL have been established in pediatric patients over 2 years of age for CT of the body and head. Use of Ultravist Injection in these age groups is supported by evidence from adequate and well controlled studies of Ultravist Injection in adults and additional safety data obtained in literature and other reports in a total of 274 pediatric patients. Of these, there were 131 children (2–12 years), 57 adolescents, and 86 children of unreported or other ages. There were 148 females, 94 males and 32 in whom gender was not reported. The racial distribution was: Caucasian 93 (33.9%), Black 1 (0.4%), Asian 6 (2.2%), and unknown 174 (63.5%). Eighty-seven of these patients were evaluated in intravenous contrast computerized tomography (CT) (n=87).

In these pediatric patients, a concentration of 300 mg iodine per mL was employed for intravenous contrast CT. Most pediatric patients received initial volumes of 1–2 mL/kg.

Optimal doses of Ultravist Injection have not been established because different injection volumes, concentrations and injection rates were not studied. The relationship of the volume of injection with respect to the size of the target vascular bed has not been established. The potential need for dose adjustment on the basis of immature renal function has not been established. In the pediatric population, the pharmacokinetic parameters have not been established.

Pediatric patients at higher risk of experiencing an adverse reaction during and after administration of any contrast agent include those with asthma, a sensitivity to medication and/or allergens, cyanotic and acyanotic heart disease, congestive heart failure, or a serum creatinine greater than 1.5 mg/dL. The injection rates in small vascular beds, and the relationship of the dose by volume or concentration in small pediatric patients have not been established. Exercise caution in selecting the dose.

The safety and effectiveness of Ultravist Injection 300 iodine per mL have not been established in pediatric patients below the age of two for CT of the body and head . The safety and effectiveness of Ultravist Injection 370 mg iodine per mL have not been established in pediatric patients of any age for CT of the body and head

Geriatric Use

Middle-aged and elderly patients, without significantly impaired renal function, who received Ultravist Injection in doses corresponding to 9–30 g iodine, had mean steady-state volumes of distribution that ranged between 30–40 L. Mean total and renal clearances were between 81–125 mL/min and 70–115 mL/min respectively in these patients, and were similar to the values found in the young volunteers. The distribution phase half-life in this patient population was 0.1 hour, the main elimination phase half-life was 2.3 hours, and the terminal elimination phase half-life was 40 hours. The urinary excretion (97% of the dose) and fecal excretion (2%) was comparable to that observed in young healthy volunteers, suggesting that, compared to the renal route, biliary and/or gastrointestinal excretion is not significant for iopromide.

Renal Impairment

In patients with renal impairment, opacification of the calyces and pelves by iopromide may be delayed due to slower renal excretion of iopromide.

A pharmacokinetic study in patients with mild (n=2), moderate (n=6), and severe (n=3) renal impairment was conducted. The total clearance of iopromide was decreased proportionately to the baseline decrease in creatinine clearance. The plasma AUC increased about 2-fold in patients with moderate renal impairment and 6-fold in patients with severe renal impairment compared to subjects with normal renal function. The terminal half-life increased from 2.2 hrs for subjects with normal renal function to 11.6 hrs in patients with severe renal impairment. The peak plasma concentration of iopromide was not influenced by the extent of renal impairment. Exercise caution and use the lowest necessary dose of Ultravist Injection in patients with renal dysfunction [see Warnings and Precautions (5.2)].

Overdosage

The adverse effects of overdosage are life-threatening and affect mainly the pulmonary and cardiovascular systems. Treatment of an overdosage is directed toward the support of all vital functions, and prompt institution of symptomatic therapy.

Iopromide binds negligibly to plasma or serum protein and can, therefore, be dialyzed.

Ultravist Injection Description

Ultravist Injection - Clinical Pharmacology

Mechanism of Action

Ultravist Injection is a nonionic, water soluble, tri-iodinated x-ray contrast agent for intravascular administration.

Intravascular injection of Ultravist Injection opacifies those vessels in the path of flow of the contrast agent, permitting radiographic visualization of the internal structures until significant hemodilution occurs.

Pharmacodynamics

Following Ultravist Injection administration, the degree of contrast enhancement is directly related to the iodine content in the administered dose; peak iodine plasma levels occur immediately following rapid intravenous injection. Iodine plasma levels fall rapidly within 5 to 10 minutes. This can be accounted for by the dilution in the vascular and extravascular fluid compartments.

Intravascular Contrast: Contrast enhancement appears to be greatest immediately after bolus injections (15 seconds to 120 seconds). Thus, greatest enhancement may be detected by a series of consecutive two-to-three second scans performed within 30 to 90 seconds after injection (that is, dynamic computed tomographic imaging).

Ultravist Injection may be visualized in the renal parenchyma within 30–60 seconds following rapid intravenous injection. Opacification of the calyces and pelves in patients with normal renal function becomes apparent within 1–3 minutes, with peak contrast occurring within 5–15 minutes.

In contrast CT, some performance characteristics are different in the brain and body. In contrast CT of the body, iodinated contrast agents diffuse rapidly from the vascular into the extravascular space. Following the administration of iodinated contrast agents, the increase in tissue density to x-rays is related to blood flow, the concentration of the contrast agent, and the extraction of the contrast agent by various interstitial tissues. Contrast enhancement is thus due to any relative differences in extravascular diffusion between adjacent tissues.

In the normal brain with an intact blood-brain barrier, contrast is generally due to the presence of iodinated contrast agent within the intravascular space. The radiographic enhancement of vascular lesions, such as arteriovenous malformations and aneurysms, depends on the iodine content of the circulating blood pool.

In tissues with a break in the blood-brain barrier, contrast agent accumulates within interstitial brain tissue. The time to maximum contrast enhancement can vary from the time that peak blood iodine levels are reached to 1 hour after intravenous bolus administration. This delay suggests that radiographic contrast enhancement is at least in part dependent on the accumulation of iodine containing medium within the lesion and outside the blood pool. The mechanism by which this occurs is not clear.

For information on coagulation parameters, fibrinolysis and complement system [see Drug Interactions (7.2)].

Pharmacokinetics

Distribution

After intravenous administration to healthy young volunteers, plasma iopromide concentration time profile shows an initial distribution phase with a half-life of 0.24 hour; a main elimination phase with a half-life of 2 hours; and a terminal elimination phase with a half-life of 6.2 hours. The total volume of distribution at steady state is about 16 L suggesting distribution in to extracellular space. Plasma protein binding of iopromide is 1%.

Iodinated contrast agents may cross the blood-brain barrier [see Warnings and Precautions (5.8)].

Metabolism

Iopromide is not metabolized.

Elimination

The amounts excreted unchanged in urine represent 97% of the dose in young healthy subjects. Only 2% of the dose is recovered in the feces. Similar recoveries in urine and feces are observed in middle-aged and elderly patients. This finding suggests that, compared to the renal route, biliary and/or gastrointestinal excretion is not important for iopromide. During the slower terminal phase, only 3% of the dose is eliminated; 97% of the dose is disposed of during the earlier phases, the largest part of which occurs during the main elimination phase. The ratio of the renal clearance of iopromide to the creatinine clearance is 0.82 suggesting that iopromide is mainly excreted by glomerular filtration. Additional tubular reabsorption is possible. Pharmacokinetics of iopromide at intravenous doses up to 80 g iodine, are dose proportionate and first order.

The mean total and renal clearances are 107 mL/min and 104 mL/min, respectively.

Specific Populations

A pharmacokinetic study was conducted in 11 patients with renal impairment [see Use in Specific Populations (8.6)].

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

Long-term animal studies have not been performed with iopromide to evaluate carcinogenic potential or effects on fertility. Iopromide was not genotoxic in a series of studies including the Ames test, an in vitro human lymphocytes analysis of chromosomal aberrations, an in vivo mouse micro-nucleus assay, and in an in vivo mouse dominant lethal assay.

Clinical Studies

Ultravist Injection was administered to 708 patients; 1 patient was less than 18 years of age, 347 patients were between 18 and 59 years of age, and 360 patients were equal to or greater than 60 years of age; the mean age was 56.6 years (range 17–88). Of the 708 patients, 446 (63%) were male and 262 (37%) were female. The racial distribution was: Caucasian 463 (65.4%), Black 95 (13.4%), Hispanic 36 (5.1%), Asian 11 (1.6 %), and other or unknown 103 (14.5%). Efficacy assessment was based on the global evaluation of the quality of the radiographs by rating visualization as either excellent, good, poor, or no image, and on the ability to make a diagnosis. Contrast CT of head and body was evaluated in three randomized, double-blind clinical trials of Ultravist Injection, 300 mg Iodine per mL, in 95 patients with vascular disorders. Visualization ratings were good or excellent in 99% of the patients; a radiologic diagnosis was made in the majority of the patients. A confirmation of contrast CT findings by other diagnostic methods was not obtained.

Ultravist Injection was evaluated in a blinded reader trial for CT of the head and body. Among the 382 patients who were evaluated with Ultravist Injection 370 mg Iodine per mL, visualization ratings were good or excellent in approximately 97% of patients.
