Advances in imaging examination of bone density and bone quality.

Bone mineral density is the primary basis for the diagnosis of osteoporosis. Bone mineral density measurement methods include dual-energy X-ray (DXA) and quantitative computed tomography (QCT). Based on traditional bone density detection equipment, the newly developed imaging detection technology can further detect the microstructures and geometric features of bones, providing important reference for exploring the pathophysiological changes, sensitive clinical diagnosis, and disease monitoring of osteoporosis.
