MDCT arthrography assessment of the severity of cartilage damage and scapholunate dissociation in regard to specific-component tears of the scapholunate interosseous ligament.

Purpose: To evaluate the distribution and severity of cartilage damage and scapholunate dissociation assessed on multi-detector computer tomography (MDCT) arthrography in a sample of patients with scapholunate interosseous ligament (SLIL) injury, in regard to component-specific tears.

Methods: We retrospectively included 37 patients with SLIL tears and 34 patients without SLIL tears who served as controls, all patients had undergone MDCT arthrography. Morphology of SLIL dorsal and volar components was graded as: normal, partial, or complete tear.

MRI characteristics of carotid bulb atypical fibromuscular dysplasia in black stroke patients.

Background And Purpose: In black stroke patients, a particular form of fibromuscular dysplasia (FMD), called atypical FMD (aFMD), is involved in stroke mechanism. The high rate of stroke recurrence under medical treatment leads to propose surgery in such patients. Regarding its location level on the carotid bulb, aFMD is often confused with atherosclerosis or free-floating thrombus.
