MR imaging of osteochondral and articular lesions.

MR imaging provides clinically useful information in assessing the elbow joint for osteochondral and articular lesions. Post-traumatic osseous abnormalities well seen by MR imaging include radiographically occult fractures, stress fractures, bone contusions, osteochondritis dissecans, and chondral defects. Intraarticular loose bodies can be identified with MR imaging, especially if fluid or contrast material are present within the elbow joint. MR imaging can also provide additional information regarding synovial osteochondritis, osteoarthritis, and bursitis about the elbow.
