Seventy-nine autopsy correlations of CT scans showed (1) excellent correlations in normal brains, but the size of the lateral ventricles consistently larger during life than after death; (2) a distinctive pattern differentiating obstructive from nonobstructive hydrocephalus; (3) infarctions appearing as areas of decreased densities of parenchyma in vascular distributions; (4) distinctive high density appearances of hemorrhages that differentiated them from infarctions and, in general, all other pathologic processes; (5) supratentorial, intraventricular, and posterior fossa tumors appearing as masses that displaced, distorted, collapsed, and enlarged normal spaces and structures such as ventricles and pineal gland; (6) 11 false-negative CT scans in some cases of brain stem infarction, brain stem hemorrhage, and small metastasis; and (7) an overall accuracy of 86.2 percent of CT scanning in correctly identifying pathology of the brain.
79例CT扫描与尸检的对照研究显示：(1) 在正常脑内两者相关性极佳，但生前侧脑室的大小始终大于死后；(2) 存在一种区分梗阻性脑积水与非梗阻性脑积水的独特模式；(3) 梗死灶在血管分布区域表现为脑实质密度减低区；(4) 出血灶呈现出独特的高密度表现，使其有别于梗死灶以及一般的所有其他病理过程；(5) 幕上、脑室内及后颅窝肿瘤表现为肿块，这些肿块使脑室和松果体等正常间隙和结构发生移位、变形、塌陷及扩大；(6) 在一些脑干梗死、脑干出血及小转移瘤病例中出现11例假阴性CT扫描结果；(7) CT扫描在正确识别脑部病变方面的总体准确率为86.2%。
