[Assessment of volumetric bone mineral density and geometry for hip with clinical CT device].

It is one of the most important challenges for preventing hip fractures to establish an accurate non-invasive assessment of hip fracture risk. Quantitative computed tomography (QCT) is able to analyze not only volumetric bone mineral density (mg/cm3) of trabecular and cortical bone compartment separately, but also geometry and biomechanical parameters in bone such as cross-sectional area, cortical bone thickness, section modulus, buckling ratio etc. The analysis of geometry and biomechanical parameters at hip could provide better prediction of hip fracture risk, better understanding pathogenesis of hip fractures, and thus better selection of drug and/or lifestyle-based interventions.
