![]() ![]() ![]() Although several studies have shown that MRI can detect early osseous changes, prospective clinical studies are needed to determine how well these early changes can predict development of clinically significant disease, and to determine whether clinical outcomes are improved by initiating therapy in persons with normal X-rays based on MRI findings. There is no adequate evidence from prospective clinical studies that clinical outcomes are improved by using MRI over standard X-rays for this indication. Magnetic resonance imaging (MRI) has become the premier orthopedic diagnostic tool used in detecting meniscal and anterior cruciate ligament (ACL) tears and has virtually replaced both arthrography and arthroscopy as the diagnostic test of choice.Īccording to established guidelines from the American College of Rheumatology (2002), disease progression in rheumatoid arthritis (RA) should be followed using standard X-rays of the extremities.
