Nineteen abnormal temporomandibular joints (TMJs) imaged with high-field-strength surface-coil MR are presented to illustrate specific changes associated with disk derangement, trauma, and previous surgery. Cases were selected from a series of 248 TMJ MR studies in 144 patients (9-68 year old, 130 females and 14 males) performed during a 5-month period. Surgical findings were available for corr...

ABduction and External Rotation (ABER) sequence in magnetic resonance (MR) arthrography of the shoulder is particularly important to better depict abnormal conditions of some glenohumeral joint structures and surrounding tissues by making imaging possible under a stress position relevant to pathologic conditions. Among the structures and tissues better depicted in this position are articular su...

Abstract Purpose of Review This paper sets out to review the past and current literature on evaluation management various types carpal instability. Recent Findings Carpal instability has many sub-types, therefore, its widely differ. There are recent studies that indicate while MRI MR arthrography mainstays for evaluation, certain CT radiographic measurements may be better at diagnosing scapholu...

433 R arthrography is the preferred imaging technique for the investigation of patients with shoulder instability [1, 2]. MR arthrography reliably shows subtle lesions of the labroligamentous complex, providing information essential to the surgeon concerning the surgery or arthroscopic repair. Most patients presenting with shoulder instability have anterior instability; in these cases, evaluati...
