Thin-section computed tomographic (CT) scans of 3 and 1.5 mm thickness were obtained using the Philips Tomoscan 310 and General Electric 8800 CT/T scanners in the study of 10 consecutive patients with progressive supranuclear palsy (PSP) and 31 patients with other diseases. Marked midbrain and moderate pontine atrophy, a dilated third ventricle, and enlarged quadrigeminal plate cisterns were observed in all PSP cases. The aqueduct was dilated in several. In six of the PSP cases, there was a striking midbrain abnormality in the form of a low-density area extending from the interpeduncular cistern toward the aqueduct. Thin-section metrizamide-enhanced cisternography of three of the six PSP cases showed that the low-density abnormality was the result of the interpeduncular cistern invaginating the atrophic midbrain.
在对10例连续性进行性核上性麻痹（PSP）患者和31例其他疾病患者的研究中，使用飞利浦Tomoscan 310和通用电气8800 CT/T扫描仪获取了厚度为3毫米和1.5毫米的薄层计算机断层扫描（CT）图像。在所有PSP病例中均观察到明显的中脑和中度脑桥萎缩、第三脑室扩张以及四叠体板池扩大。部分病例中导水管扩张。在6例PSP病例中，存在一种显著的中脑异常，表现为从脚间池向导水管延伸的低密度区域。对6例PSP病例中的3例进行的薄层甲泛葡胺增强脑池造影显示，低密度异常是脚间池向萎缩的中脑内陷的结果。
