MRIs can be harmful if you have metal inside your body such as joint replacements or a pacemaker. Make sure your doctor knows of any internal metal before the test. Some people may also have an allergic reaction to the contrast dye. Talk to your doctor about any allergies you have. Also, let your doctor know if you have liver or kidney problems. These may make it difficult for your body to get rid of the contrast.

Description of the Test
If contrast is used, a small IV needle will be inserted into your hand or arm before you are moved into the MRI machine. The contrast will be injected during one set of images. It helps to make some organs and vessels easier to see on the pictures. You might have an allergic reaction to the dye, but this is rare
You will lie on a special table. This table will be moved inside the opening of the MRI machine. Most MRIs consist of 2-6 sets of images. Each one will take between 2-15 minutes. You will need to lie still while the images are being taken. You may need to hold your breath briefly. Technicians will communicate with you through an intercom from another room.
You will be asked to wait at the facility while the images are examined. The technician may need more images.
If you took a sedative, do not drive or operate machinery until it wears off.
