Magnetic Resonance Imaging (MRI or NMR scan)
Magnetic Resonance Imaging (MRI) is a noninvasive imaging technique. This test is similar to a CT scan but uses magnetism instead of X-rays to build up cross-sectional pictures of your body. It is used to view organs, soft-tissue, bone, and other internal body structures. In an abdominal MRI, the person's body is exposed to radio waves while in a magnetic field. Cross-sectional pictures of the abdomen are produced by energy emitted from hydrogen atoms in the body's cells.
An individual is not exposed to harmful radiation during this test.
