作者对18例脑动脉瘤进行三维CT血管造影(3-DCTA)检查。其中女性11例,男性7例,年龄31～70岁。所有病人因蛛网膜下腔出血经动脉血管造影(LA-DSA)或CT和MRI诊断为大型或巨大型动脉瘤。15例以Willis环为中心横断扫描。3例因动脉瘤或动静脉畸形夹闭后为避免金属夹伪影采用冠状扫描。CT影像经磁带通过计算机进行三维重建。
The author of 18 cases of cerebral aneurysm by three-dimensional CT angiography (3-DCTA) examination. Including 11 females, 7 males, aged 31 to 70 years. All patients were diagnosed with large or giant aneurysms by arterial angiography (LA-DSA) or CT and MRI due to subarachnoid hemorrhage. Fifteen patients were transected with the Willis ring as the center. 3 cases of aneurysm or arteriovenous malformation after clipping to avoid metal clip artifacts using coronal scan. CT images through the computer through a three-dimensional reconstruction of the computer.
