An application of computed tomography (CT) is described in which multiplanar high resolution images of the terminal carotid and basilar arteries are obtained. This has been applied in a series of 32 patients with IIIrd nerve palsy in whom the underlying pathology was thought to be a posterior communicating artery aneurysm. The results of the CT were compared with conventional angiography. Seventeen aneurysms were detected in 13 patients by CT and all were confirmed by angiography. Vessels considered to be normal on CT were confirmed to be normal by angiography. This CT technique is a simple non invasive first line investigation for IIIrd nerve palsy with the ability to exclude or predict an aneurysm.
本文描述了计算机断层扫描（CT）的一种应用，即获取颈内动脉终末段和基底动脉的多平面高分辨率图像。这一技术已应用于32例动眼神经麻痹患者，这些患者被认为潜在病因是后交通动脉瘤。将CT结果与传统血管造影结果进行了比较。CT在13例患者中检测出17个动脉瘤，所有这些动脉瘤均经血管造影证实。CT显示正常的血管经血管造影也证实正常。这种CT技术是一种简单的非侵入性一线检查方法，可用于排除或预测动眼神经麻痹患者是否存在动脉瘤。
