Transaxial CT scans of 100 patients with hydrostatic hydrocephalus and 50 patients with hydrocephalus ex vacuo have been reviewed with respect to measurements of: frontal horn ratio, width of the temporal horns, width of the third ventricle, width of cerebral fissures and sulci. The diagnosis of hydrostatic hydrocephalus is probable when (a) both temporal tips are visualized and measure 2 mm or greater in width and the sylvian and interhemispheric fissures and cerebral sulci are not visible, or (b) there is visualization of temporal horn tips measuring 2 mm or greater in width and the lateral ventricles are symmetrically enlarged with the frontal horn ratio 0.50 or more.
对100例交通性脑积水患者和50例脑外积水患者的经轴位CT扫描进行了回顾，测量内容包括：额角比率、颞角宽度、第三脑室宽度、脑沟和脑裂宽度。当出现以下情况时，交通性脑积水的诊断可能性较大：（a）双侧颞叶尖部可见且宽度测量为2mm或更宽，且外侧裂和大脑纵裂以及脑沟不可见；或（b）可见宽度为2mm或更宽的颞叶角尖部，且侧脑室对称扩大，额角比率为0.50或更高。
