MRI (Magnetic Resonance Imaging) General Info | Angiography | Breast | Head | Musculoskeletal | Prostate | Spine | View Full Exam List What is an MRI scan?Magnetic resonance imaging (MRI) is an imaging method that uses radio waves and the natural magnetic field emitted by your body to diagnose many types of injuries and conditions. MRI is very valuable for diagnosing a broad range of conditions in all parts of the body, including neurological disorders, cancer, heart and vascular diseases, stroke, and joint and musculoskeletal disorders. An MRI exam is painless and does not involve the use of radiation in order to create a picture or "image" of the body part being evaluated. Contrast material or "dye" is sometimes injected through a vein to highlight blood vessels and soft-tissue masses. How is MRI used? MRI is very useful for visualizing the soft-tissue that surrounds bone. It is excellent for analyzing spinal and joint problems and diagnosing sports-related injuries affecting the knee, shoulder, hip, elbow and wrist. MRI is also used to non-surgically view the heart, aorta, coronary arteries and blood vessels for diagnosing coronary artery disease and heart conditions. Organs of the chest and abdomen can also be examined in great detail. More recently, MRI has been used in conjunction with traditional mammography to aid in the diagnosis and management of breast cancer.
