In this study, the possibility of non-invasive, three-dimensional demonstration of aneurysms of the basal cerebral arteries by means of spiral CT was investigated. The first step was to obtain exact definition of optimal examination parameters. Angio CTs at appropriate levels were performed on 10 subjects and time/density curves of the arterial and venous phases obtained in order to optimise the beginning of the arterial spiral CT series. The second step in this investigation was to examine 7 patients; in 6 of these basal aneurysms had been demonstrated by DSA. By means of multiplanar three-dimensional reconstruction from the data of the spiral CT it was possible to demonstrate 7 aneurysms with a diameter between 5 and 18 mm. Their position and relationship to the bony skull was also shown.
在本研究中，对通过螺旋CT进行无创性三维显示脑基底动脉动脉瘤的可能性进行了研究。第一步是准确确定最佳检查参数。对10名受试者进行了适当层面的血管CT检查，并获取了动脉期和静脉期的时间/密度曲线，以便优化动脉螺旋CT扫描序列的起始时间。本研究的第二步是检查7名患者；其中6名患者的基底动脉瘤已通过数字减影血管造影（DSA）证实。通过对螺旋CT数据进行多平面三维重建，能够显示7个直径在5至18毫米之间的动脉瘤。还展示了它们的位置以及与颅骨的关系。
