有关网状骨微结构的准确信息有助于预测病人骨折的危险性。目前远端桡骨3D-QCT已经用于这一目的。这种新方法的有效性受CT图像空间分辨率的制约,而分辨率又受限于X射线的剂量。局部断层成像只对感兴趣区进行X射线扫描,因此可以提供解决这一问题的有效手段。本文对局部断层成像
Accurate information about the microstructure of reticular bones can help predict the risk of fractures in patients. Currently distal 3D-QCT has been used for this purpose. The effectiveness of this new method is limited by the spatial resolution of the CT image, which in turn is limited by the dose of X-rays. Local tomography performs an X-ray scan of the region of interest only and can therefore provide an effective means of solving this problem. This article on the local tomography
