What is Magnetic Resonance Imaging?
MRI is a way to look inside the body by using a magnetic field and radio waves instead of x-ray. Because MRI can target specific soft tissues, it is especially valuable in looking at breast tissue and breast cancers. In many cases, MRI gives different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan.
What to Expect During a Breast MRI
Before the procedure, the technologist will place an IV in your arm as this test requires an injection of a magnetic dye called gaolinium.
The technologist will then help you position yourself face down on the MRI table. This table has space for your breasts and a face rest with an open area that allows you to breathe freely. Your arms will be placed above your head. Earplugs will be offered to you before the test starts.
The table will glide into a narrow tunnel to begin the scan. You will hear fans that circulate air around you. There will be plenty of light inside and an intercom system that allows you to hear and talk to the technologist throughout the test.
When the scanning begins, you will hear loud thumps, knocks and humming sounds. These are typical sounds during a scan.
