Magnetic Resonance Imaging Of The Chest
What you should know
Magnetic Resonance Imaging Of The Chest (Precare) Care Guide
A magnetic resonance imaging scan is also called an MRI. It uses magnetic fields and radio waves to take pictures of the inside of your body. A chest MRI is done to see blood vessels, tissue, and bones in your chest. It will also show organs, such as your heart and lungs.
Care AgreementYou have the right to help plan your care. Learn about your health condition and how it may be treated. Discuss treatment options with your caregivers to decide what care you want to receive. You always have the right to refuse treatment.
- The contrast dye may cause a rash, itching, or trouble breathing. If you have diabetes, your risk for kidney damage may increase if contrast dye is used. Metal in or on your body may cause a burn or other injury. A metal device may move out of place during the MRI. An MRI can make medical devices work incorrectly or stop working. You may have short-term hearing loss after an MRI.
- Without an MRI scan, your caregiver may not learn about your condition or know if treatments are working. Your condition may get worse.
Before your procedure:
- Write down the correct date, time, and location of your procedure.
- Ask your caregiver if you need to stop using aspirin or any other prescribed or over-the-counter medicine before your procedure or surgery.
- Bring your medicine bottles or a list of your medicines when you see your caregiver. Tell your caregiver if you are allergic to any medicine. Tell your caregiver if you use any herbs, food supplements, or over-the-counter medicine.
- Tell your caregiver if you know or think you might be pregnant.
The night before your procedure:
Ask caregivers about directions for eating and drinking.
The day of your procedure:
- Ask your caregiver before taking any medicine on the day of your procedure. These medicines include insulin, diabetic pills, high blood pressure pills, or heart pills. Bring a list of all the medicines you take, or your pill bottles, with you to the hospital.
- You or a close family member will be asked to sign a legal document called a consent form. It gives caregivers permission to do the procedure or surgery. It also explains the problems that may happen, and your choices. Make sure all your questions are answered before you sign this form.
- The magnets may cause harm if you have metal in or on your body. Tell the caregiver if you have an implant, such as a pacemaker, defibrillator, stent, insulin pump, or cochlear implant. Tattoos, permanent eye liner, and some intrauterine devices (IUDs) may also contain metal. You will also be asked to remove items such as jewelry, a belt, or a hair clip. If you use a medicine patch, remove it before the test. You can put it back on after the MRI.
- Contrast dye may be used to help caregivers see blood vessels or tissue more clearly. Tell the caregiver if you have ever had an allergic reaction to contrast dye.
- Caregivers may insert an intravenous tube (IV) into your vein. A vein in the arm is usually chosen. Through the IV tube, you may be given liquids and medicine.
What will happen:
- You will lie on a narrow table. You may be given earplugs or headphones to decrease the noise of the MRI. The table will be moved into the hole in the middle of the machine.
- You will hear loud banging or tapping noises as the machine takes pictures. The noise is caused by the magnets in the machine. You will need to lie still during the MRI scan. Caregivers may tell you to hold your breath or avoid swallowing for a few seconds during the scan. When the scan is done, the table will be moved out of the machine.
After your procedure:
Caregivers will monitor you closely for any problems. Do not get out of bed until your caregiver says it is okay. When your caregiver sees that you are okay, you will be able to go home or be taken to your hospital room.
Contact a caregiver if
- You cannot make it to your procedure.
- You think you may be pregnant.
