Ultra-Technekow V4 Dosage

Sodium Pertechnetate Tc 99m is administered by intravenous injection. When imaging the nasolacrimal drainage system, instill the Sodium Pertechnetate Tc 99m by the use of a device such as a micropipette or similar method which will ensure the accuracy of the dose.

For imaging the urinary bladder and ureters (direct isotopic cystography), the Sodium Pertechnetate Tc 99m is administered by direct instillation aseptically into the bladder via a urethral catheter, following which the catheter is flushed with approximately 200 mL of sterile saline directly into the bladder.

The suggested dose ranges employed for various diagnostic indications in the average ADULT PATIENT (70 kg) are as follows:

Vesico-ureteral imaging: 18.5 to 37 MBq (0.5 to 1 mCi)
Thyroid gland imaging: 37 to 370 MBq (1 to 10 mCi)
Salivary gland imaging: 37 to 185 MBq (1 to 5 mCi)
Nasolacrimal drainage system: Maximum dose of 3.7 MBq (100 µCi)

The recommended dosages in PEDIATRIC PATIENTS are:

Vesico-ureteral imaging: 18.5 to 37 MBq (0.5 to 1 mCi)
Thyroid gland imaging: 2.22 to 2.96 MBq (60 to 80 µCi) per kg body weight

The patient dose should be measured by a suitable radioactivity calibration system immediately prior to administration.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. If the solution is discolored, discontinue use of the generator immediately. The solution to be administered as the patient dose should be clear, colorless, and contain no particulate matter.
