The purpose of this study was to define the role of three-dimensional (3D) computed tomography (CT) in the head and neck diseases with bony abnormalities. Thirty-two patients were examined with a low dose radiation technique. Three-dimensional CT clearly delineated bony lesions in 27 of 32 patients. Three-dimensional CT could not demonstrate subtle bony erosions infiltrated by tumor, a temporal bone fracture, and a blow-out fracture, although two-dimensional (2D) images obtained before the 3D reconstructions clearly depicted those lesions. These two kinds of CT technique were thought to be complimentary.
本研究的目的是确定三维（3D）计算机断层扫描（CT）在伴有骨质异常的头颈部疾病中的作用。32例患者采用低剂量辐射技术进行检查。三维CT在32例患者中的27例中清晰显示了骨质病变。尽管在三维重建之前获得的二维（2D）图像清楚地描绘了这些病变，但三维CT无法显示被肿瘤浸润的细微骨质侵蚀、颞骨骨折和爆裂性骨折。这两种CT技术被认为是互补的。
