OBJECTIVE The goal of this study was to compare MR imaging with arthroscopy in evaluating triangular fibrocartilage (TFC) pathology. MATERIALS AND METHODS The results of 178 MR imaging examinations of the wrist were independently reviewed by two musculoskeletal radiologists who were unaware of the the clinical history, including any subsequent surgery.(More)
The integrity of the ligamentous network of the wrist is critical, as disruption of this network may result in carpal instability and pain. The extrinsic (radiocarpal) and intrinsic (intercarpal) ligaments that maintain carpal stability can be evaluated with magnetic resonance (MR) imaging. The major extrinsic ligaments are the radioscaphocapitate,(More)
The diagnostic efficacy of (1) combined three-phase bone scintigraphy and In-111 labeled WBC scintigraphy (Bone/WBC), (2) MRI, and (3) conventional radiography in detecting osteomyelitis of the neuropathic foot was compared. Conventional radiography was comparable to MRI for detection of osteomyelitis. MRI best depicted the presence of osteomyelitis in the(More)
The triangular fibrocartilage complex (TFCC) is a complex anatomic and biomechanical structure. Injury to the TFCC is a recognized cause of ulnar wrist pain. The TFCC may be injured in its horizontal portion, in its peripheral portions, or at its attachments. In the Palmer classification, TFCC lesions are categorized as traumatic or degenerative. Traumatic(More)
This article describes MR imaging of acute and chronic injuries of the ankle and foot, elbow, and hand and wrist. Conditions discussed include ligament and tendon injuries, fractures and bone bruises, osteochondral defects, foreign bodies, and posttraumatic ganglions. Other topics covered include fasciitis, nerve and muscle injuries about the elbow, and(More)
Twenty-six normal wrists in young adults were studied with magnetic resonance (MR) imaging. The following conclusions were drawn regarding normal anatomic features: (a) Multiple slips of the abductor pollicis longus tendon simulate longitudinal tears; (b) the extensor pollicis longus and extensor carpi ulnaris tendons normally demonstrate increased signal(More)
Over the last several decades bone scanning has been used extensively in the evaluation of oncology patients to detect bone involvement. It can provide information about disease location, prognosis, and the effect of therapy. Bone scanning offers the advantages of whole body evaluation and the detection of lesions earlier than other techniques. However, as(More)
Magnetic resonance (MR) and ultrasound (US) imaging are currently touted for assessment of rotator cuff disease. Optimum clinical imaging techniques include use of (a) a 1.5-T MR imaging unit with small planar coils, proton-density-weighted and T2-weighted fast spin-echo sequences, and 10-12-cm fields of view (yielding 400-470 x 500-625-microm in-plane(More)
