Radiography versus computed tomography for osseous staging of Kienböck's disease.

This retrospective study compared the diagnostic accuracy of conventional radiography (CR) and computed tomography (CT) in classifying Kienböck's disease (KD) according to Lichtman staging. Besides age, cartilage condition and vascularity, bone morphology is important in choosing the most appropriate treatment in KD. In 278 patients, two musculoskeletal radiologists performed a consensus reading of 281 lunate necroses according to the Lichtman classification, based on CR and CT.

Associations of gestational diabetes and proton density fat fraction of vertebral bone marrow and paraspinal musculature in premenopausal women.

Background And Objective: Fat content in bones and muscles, quantified by magnetic resonance imaging (MRI) as a proton density fat fraction (PDFF) value, is an emerging non-invasive biomarker. PDFF has been proposed to indicate bone and metabolic health among postmenopausal women. Premenopausal women with a history of gestational diabetes (GDM) carry an increased risk of developing type 2 diabetes and an increased risk of fractures.
