HR-QCT assessment of bone beyond bone mineral density

摘要

Central DXA of the lumbar spine and proximal femur is the preferred methodfor bone mineral density (BMD) testing. Despite the fracture risk statistics,osteoporosis testing with dual energy X-ray absorptiometry (DXA) remainsunderused. However, BMD can also be assessed with other radiologic imagingtools, such as quantitative computed tomography (QCT) that may beavailable when access to DXA is restricted.
