title: Utilization and reporting of bone densitometry: what can the musculoskeletal radiologist do to help, rather than to hurt?
abstract: Osteoporosis is a highly prevalent disease that predisposes patients to fragility fractures. These fractures carry serious risks, including increased mortality and the potential loss of functional independence. Effective treatments for osteoporosis are available, but these should be initiated before a fragility fracture actually occurs; to do so, osteoporosis must be diagnosed while it is still asymptomatic. The gold standard screening test used to detect low bone mass is dual-energy x-ray absorptiometry (DXA). Despite its clinical importance, the DXA report is sometimes neglected by radiologists-as though it were somehow less significant in diagnosis than our other modalities. If musculoskeletal radiologists are to help, rather than to hurt, we must raise the profile of this critical test with evidence-based utilization and coherent reporting: detailed recommendations for doing so are available from professional organizations such as the International Society for Clinical Densitometry and the National Osteoporosis Foundation. This brief survey will seek to remind the radiologist that a good densitometry report requires more than just copying numbers from a scanner.
