Magnetic resonance imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body. An MRI scanner is a large tube that contains powerful magnets. You lie inside the tube during the scan.
What shows up on an MRI?
An MRI, or magnetic resonance imaging, is a highly technical and informative way of imaging the human body. The images that are created can be very useful to your doctors for detecting structural abnormalities of different organs, inflammation of soft tissue, and tears of muscle or ligaments, among other problems.

What is an MRI with contrast?
When injected into the body, gadolinium contrast medium makes certain tissues, abnormalities or disease processes more clearly visible on a magnetic resonance imaging (MRI) scans. Gadolinium based contrast medium is sometimes called an MRI contrast medium or agent.
