Abstract

A clinical study comparing the relative sensitivities of computed tomography, skull radiography, and radionuclide scanning in the detection of skull metastases indicated that CT was the least sensitive of these three modalities. CT could however detect a majority of lesions if scans were viewed at appropriate window settings. Phantom studies showed that the limitations of CT can be related to limited spatial resolution, the density of the lesions, partial volume averaging, and plane of section.

摘要

一项比较计算机断层扫描（CT）、颅骨X线摄影和放射性核素扫描在检测颅骨转移瘤方面相对敏感性的临床研究表明，CT是这三种检查方式中敏感性最低的。然而，如果在适当的窗宽设置下观察扫描图像，CT能够检测出大多数病变。模型研究显示，CT的局限性可能与空间分辨率有限、病变密度、部分容积效应和平扫层面有关。
