Test preparation: MRI and CT
Each imaging test is different. You may be asked not to eat or drink anything other than water or clear liquids (like apple juice) for three or four hours before an MRI or CT scan. Some contrast MRI or CT scans may require you to drink the contrast liquid before your scan at a specific time. If the MRI or CT scan is without contrast, no special instructions are needed. If you have any medical devices such as implants, pacemakers, metal clips, or stents, these may affect the test, and you must inform our radiologist. Not all patients are appropriate candidates for contrast dye, and you will be asked a set of questions to ensure the dye is safe to administer. These tests are not performed on pregnant women, and contrast dye cannot be administered if you are breastfeeding.
