Here you can find preparation instructions for your upcoming MRI, CT or X-ray.
MRI does not utilize any form of ionizing radiation, so no special preparation is needed. You may eat normally and take your regular medication. Please wear comfortable clothing, like sweats. Clothing with zippers, metal buttons or snaps cannot be worn. This includes underwire bras as well. If needed, a cotton dressing gown will be available for you to use.
Because of the potentially harmful effects associated with all metallic objects in a magnetic field, you should check with your physician or MRI Technologist if you have:
- Ear implants
- Surgical staples
- Aneurysm clip(s)
- Implanted drug infusion devices
- Worked as a welder or grinder of metal
With some examinations, an injection into a vein is required. The MRI technologist will explain the procedure further if your exam requires this.
Some CT scans require the use of a contrast medium. Given intravenously, the contrast agent highlights certain body parts to enable the radiologist to better see any abnormalities. CT scans of the abdomen and pelvis often require the patient to drink a barium-based liquid to outline the intestines for better viewing.
In advance of your exam, please inform your radiologist or technologist if you are:
- Have had a previous adverse reaction to iodine contrast injection
- Have renal disease
- Are over 65
- Have asthma and use an inhaler 2 or more times per day
- Are diabetic and taking glucaphage
If you are pregnant, please tell your doctor or a patient representative before your test.
