MRI is an advanced imaging technique that uses a powerful magnetic field, radio waves, and computer software to create detailed, cross-sectional pictures of your body's internal organs and structures.
Computerized tomography (also known as a CAT scan) is a diagnostic medical test that helps radiologists examine diseased tissue in order to diagnose diseases such as cancer, lymphoma, and appendicitis.
