It may at times be difficult to separate supra- from infratentorial and intra- from extraaxial pathology on the basis of axial transverse computed tomography (CT) scans. Coronal CT scans may be quite useful in more accurate localization of compartments. Three head injured patients with subdural hematomas were studied with axial transverse CT scans. In addition to the typical appearance of subdural hematomas, unusually shaped areas of increased attenuation were noted in the region of the tentorium cerebelli separate from the mass of the subdural collection. Coronal scans confirmed the supratentorial, extraaxial collection as an extension of the subdural hematoma into the supratentorial subdural space.
有时，基于轴向横断计算机断层扫描（CT）图像，区分幕上与幕下病变以及轴内与轴外病变可能会很困难。冠状位CT扫描对于更准确地定位这些腔隙可能非常有用。对三名患有硬膜下血肿的头部受伤患者进行了轴向横断CT扫描研究。除了硬膜下血肿的典型表现外，在小脑幕区域还发现了与硬膜下血肿块分开的异常形状的高密度区。冠状位扫描证实，幕上轴外血肿是硬膜下血肿延伸至幕上硬膜下间隙所致。
