Definition: Magnetic resonance imaging (MRI) is a noninvasive way to take pictures of the body.
Unlike x-rays and computed tomographic (CT) scans, which use radiation, MRI uses powerful magnets and radio waves. The MRI scanner contains the magnet. The magnetic field produced by an MRI is about 10 thousand times greater than the earth's. The magnetic field forces hydrogen atoms in the body to line up in a certain way (similar to how the needle on a compass moves when you hold it near a magnet). When radio waves are sent toward the lined-up hydrogen atoms, they bounce back, and a computer records the signal. Different types of tissues send back different signals.
Alternative Names: Magnetic resonance imaging; Nuclear magnetic resonance (NMR) imaging
Definition: A computed tomography (CT) scan of the pelvis is an imaging method that uses x-rays to create cross-sectional pictures of the organs inside the pelvis (liver, kidneys, gallbladder, pancreas, and bladder, prostate, lymph nodes, and pelvic bones).
