It is not infrequent that in the evaluation of the angiograms of patient with aneurysms of the brain vessels the wish for a better discernability of details arises: exact demonstration of the direction and shape of an aneurysm, differenciation between vascular loop and aneurysm, direction of the course of an aneurysm, discernability of small aneurysms, etc. To this end, various radiological methods are being employed such as the substraction technique or the enlargement angiography. The best technical solution existing at present is the tomography of the angiographic examination. This answers all above mentioned questions. However, the method requires the availability of the respective device; it cannot be performed with a conventional tomograph. The great value it has for the surgeon employing microsurgery is demonstrated by some pictures. The question whether the gain which is obtained from this technique for the operation is compatible with the possible hazards for the aneurysm carrier caused by transport and time delay can only be decided in the individual case. The optimum solution is the existence of an angiotomographic unit in all special departments where neuroradiological aneurysms diagnose are established.
在评估脑血管动脉瘤患者的血管造影照片时，人们常常希望能更清晰地辨别细节：精确显示动脉瘤的方向和形状、区分血管环和动脉瘤、动脉瘤的走行方向、小动脉瘤的可辨别性等。为此，人们采用了各种放射学方法，如减法技术或放大血管造影术。目前现有的最佳技术解决方案是血管造影检查的断层扫描。这能回答上述所有问题。然而，该方法需要有相应的设备；无法用传统断层扫描仪进行。一些图片展示了它对采用显微外科手术的外科医生的巨大价值。从该技术在手术中获得的益处是否与因转运和时间延迟给动脉瘤患者带来的潜在风险相匹配，只能根据具体病例来决定。最佳解决方案是在所有设立神经放射学动脉瘤诊断的专科科室都配备血管断层摄影设备。
