MRI (magnetic resonance imaging) is a method used by physicians to visualize internal organs of the human body and obtain diagnostic information.
MRI uses a combination of magnetic fields, radio waves, and computers to generate images of the body in any plane. The procedure is completely noninvasive and 100% painless. There are not any know side effects from the MRI procedure, and all of the images from the scan are produced without the use of ionizing radiation, so patients are not exposed to any radiation during their procedure.
MRI imaging is used for virtually all parts of the body. It is the primary imaging modality for the evaluation of diseases of the brain and spine. It is effective in depicting abnormalities of the eye, paranasal sinuses, throat, salivary glands, and the thyroid.
MRI is the method of choice for imaging of the musculoskeletal system and is widely used for evaluation of the shoulder, elbow, wrist, hip, knee, and ankle. It can also accurately depict abnormalities within the bone marrow. It has many applications in the cardiovascular system.
