Opportunistic Screening for Osteoporosis Using Body CT Scans Obtained for Other Indications: the UW Experience

摘要: Low bone mineral density (osteoporosis and osteopenia) leading to fragility fractures is associated with significant morbidity mortality in our aging population. This condition grossly underdiagnosed due both insufficient screening its silent nature prior complicating fractures. Body CT scans are commonly obtained among older adults for a wide variety of indications contain rich data regarding health that often ignored. At the University Wisconsin, we have sought harness this information “opportunistic” osteoporosis screening. In article, review various CT-based approaches taken date, including routine assessment spine vertebral trabecular density, as well hip, deriving femoral neck T-scores essentially equivalent dual-energy x-ray absorptiometry (DXA). Future directions research clinical implementation also discussed.
