Explanation of the Exam
In conjunction with conventional x-ray exams, MRI of the joints has become a powerful tool to diagnose diseases of bone, cartilage, tendons, ligaments, and the synovial lining of joints.
The patient lies on a special table inside the MRI scanner, with a radio receiver antenna, or "coil", over the body part being scanned. A series of pictures are taken, each set taking anywhere from a few seconds to 10 minutes. Up to 10 of these series are obtained, each designed to bring out a specific feature of the tissue being imaged and/or changing the orientation of the slice images. A special kind of contrast, different from that used in x-ray or CT examinations, may be injected by vein or directly into the joint being examined.
