 According to the definition of osteoporosis proposed by the United States National Institutes of Health (NIH), bone strength reflects the integration of two components:bone mass (bone mineral density[BMD]) and bone quality. BMD measured by dual-energy X-ray absorptiometry (DXA) is widely used as a basis for diagnosing osteoporosis and evaluating the efficacy of treatment. However, BMD measurements alone are of limited value in predicting fractures. In this study we evaluated the quality of images of trabecular microstructure in excised human vertebrae. Within the limits of clinically available radiation sets, especially a slice thickness of 700μm, multi-detector-row computed tomography (MDCT) provided the best image quality, and the data obtained were the most highly correlated with the microCT data.
