Definition & Meaning of "magnetic resonance imaging"

What is a "magnetic resonance imaging"?

A magnetic resonance imaging (MRI) is a medical imaging technique that uses strong magnets and radio waves to create detailed pictures of the inside of the body. Unlike X-rays, MRI does not use harmful rays or radiation. During the test, the patient lies on a table that slides into a large, tube-shaped machine. The machine creates images of organs, tissues, and structures, allowing doctors to see and evaluate areas such as the brain, spine, and joints. An MRI is often used to diagnose and monitor conditions like injuries, tumors, or diseases of the organs and soft tissues.
