In this review article current developments and applications in quantitative osteoporosis imaging are presented. Developments in the field of DXA include geometrical parameters of the proximal femur such as the "hip axis length" and new ROIs to determine BMD. Advances in QCT are new volumetric techniques to quantify BMD at the lumbar spine and the proximal femur. In addition techniques to determine BMD in standard contrast-enhanced abdominal computed tomography studies are described. Currently with the new bone quality concept in full bloom techniques to quantify trabecular bone architecture as new surrogates of bone strength are of increasing significance. Spatial high-resolution techniques such as magnetic resonance imaging and new computed tomography techniques have shown their potential in assessing trabecular bone structure. In addition ultrasound is considered a low-cost technique to explore bone quality.
在这篇综述文章中，介绍了定量骨质疏松成像的当前发展和应用。双能X线吸收法（DXA）领域的发展包括股骨近端的几何参数，如“髋轴长度”，以及用于确定骨密度（BMD）的新感兴趣区域（ROI）。定量计算机断层扫描（QCT）的进展是用于量化腰椎和股骨近端骨密度的新容积技术。此外，还描述了在标准对比增强腹部计算机断层扫描研究中确定骨密度的技术。目前，随着新的骨质量概念的蓬勃发展，作为骨强度新替代指标的量化小梁骨结构的技术变得越来越重要。空间高分辨率技术，如磁共振成像和新的计算机断层扫描技术，已显示出它们在评估小梁骨结构方面的潜力。此外，超声被认为是一种探索骨质量的低成本技术。
