MRI Scan


Updated October 29, 2009

Definition: The MRI, an abbreviation for magnetic resonance imaging, uses magnetic signals to create image "slices" of the human body. Like all imaging techniques, an MRI scan creates images based on differences between types of tissues. The MRI shows us the different tissues, and thus creates an image inside the body.

An MRI scan is often used to study nerves, muscles, ligaments, bones, and other tissues in the body; the detail of the study can be quite incredible. An MRI is often used to evaluate the possibility of injuries to ligaments and tendons. Problems in the spine, such as a disc herniation are seen well on an MRI image. Masses and tumors within soft tissues can also be evaluated with MRI.
