The Added Value of Bone Microstructure Assessment in the Management of Osteoporotic Bone

1. To assess the clinical utility of trabecular bone score (TBS) on fracture risk prediction including the new version (TBS V4) and future TBS versions at the spine and hip. 2. To assess the clinical utility of TBS software as a potential treatment outcome: sensitivity to change over time and following osteoporosis therapy. 3. To compare TBS to other imaging modalities of bone structure such as quantitative computed tomography (QCT) in fracture risk prediction and response to osteoporosis therapy.
