The contrast material used for an MRI exam is called gadolinium. You may have to swallow the contrast, or you may have an intravenous (IV) catheter put in a vein in your arm so the contrast can be given into your bloodstream. Sometimes a contrast material is used for MRI imaging. In some cases, you can arrange to have an open MRI which allows more space around your body (see the next section). Sometimes talking with the technologist or a patient counselor, or seeing the MRI machine before the test can help. If being in a small, enclosed space is a problem for you (you have claustrophobia), you might need to take medicine to help you relax while in the scanner. You donвЂ™t usually need to follow a special diet or do anything to get ready for an MRI, but follow any instructions you are given. MRI scans are most often done on an outpatient basis, so you donвЂ™t have to be in a hospital to get one. The stronger signals give clearer pictures. Once absorbed by the body, the contrast speeds up the rate at which tissue responds to the magnetic and radio waves. A computer converts these signals them into a black and white picture.Д¬ontrast materials can be put into the body through a vein to clearer images. The machine uses a powerful magnetic force and a burst of radiofrequency waves to pick up signals from the nuclei (centers) of hydrogen atoms in your body. You lie on a table that slides into the tube, and the machine surrounds you with a powerful magnetic field. Learn more about breast MRI.) How does MRI work?ДЄn MRI scanner is a long cylinder or tube that holds a large, very strong magnet. (A specific kind of MRI can be used to look inside the breast.

MRI images can also help doctors plan treatment such as surgery or radiation therapy. MRI can also be used to look for signs that cancer may have metastasized (spread) from where it started to another part of the body.

Using MRI, doctors can sometimes tell if a tumor is or isnвЂ™t cancer. An MRI with contrast dye is the best way to see brain and spinal cord tumors. MRI is very good at finding and pinpointing some cancers. MRI creates pictures of soft tissue parts of the body that are sometimes hard to see using other imaging tests. An MRI scan takes cross-sectional slices (views) from many angles, as if someone were looking at a slice of your body from the front, from the side, or from above your head. But MRI uses strong magnets to make the images вЂ“ not radiation. MRI creates cross-section pictures of your insides. But, itвЂ™s very important to tell your doctor and the technologist (the person who does the test) if you have any metal in your body. MRI is painless and you donвЂ™t have to do anything special to get ready for this test. MRI also can help doctors plan cancer treatment, like surgery or radiation. MRI (also known as magnetic resonance imaging, magnetic resonance, MR, and nuclear magnetic resonance imaging) helps doctors find cancer in the body and look for signs that it has spread.
