摘　　要：目的探讨多层螺旋CT血管造影(MSCTA)对脑动脉瘤的诊断价值。方法对临床诊断为脑动脉瘤患者18例行MSCTA检查,17例行DSA检查,18例行手术。MSCTA用最大密度投影(MIP)及容积重建(VR)法进行图像后处理,与DSA检查及手术结果相比较。结果18例患者中,1例行MSCTA检查发现右大脑中动脉小动脉瘤,未行DSA而直接行手术治疗;17例患者MSCTA检查发现18个动脉瘤,DSA检查发现18个,手术证实为19个。MSCTA1个后交通动脉瘤未检出,DSA检查1个前交通动脉瘤未检出。MSCTA检查显示动脉瘤的部位、大小、瘤颈结构及周围血管的关系与手术结果基本一致,诊断符合率为95%。结论MSCTA对脑动脉瘤的诊断准确率高,而且对脑动脉瘤周围血管的关系显示良好,并对动脉瘤的临床治疗有较高的指导价值。Objective To evaluate M-spiral CT angiography(MSCTA) in the screening of cerebral artery aneurysms.Methods MSCTA was performed in 18 patients with cerebral artery aneurysms,17 cases were examined by digital subtraction angiography(DSA),18 cases underwent surgery.MSCTA images were reconstruct by using maximum intensity projection(MIP) and volume reconstruction(VR).The result were compared with DSA and operation.Results One case was examined by MSCTA and proved by operation.in the 17 patients 18 cerebral artery aneurysms were detected by MSCTA,18 aneurysms by DSA,19 aneurysms proved by operation.MSCTA and DSA has lost 1 aneurysm each other.cerebral artery aneurysm's site、shape and the relation with the other arters were very clear in MSCTA.The true positive diagnosis of aneurysms using MSCTA was 95%.Conclusion MSCTA can not only diagnose cerebral artery aneurysms accurately but also can show the relation with the aneurysm and arterys around,has high directive value in clinical trial.
