目的：探讨多层螺旋 CT 血管造影技术（multislice spiral CT angiography，MSCTA）在诊断颅内动脉瘤中的应用价值。方法对动脉瘤性蛛网膜下腔出血患者40例采用 MSCTA 诊断颅内动脉瘤，并以数字减影血管造影（digital subtraction angiography，DSA）作为金标准，评价 MSCTA 对颅内动脉瘤诊断的灵敏性、特异性及准确性。结果40例患者中共在32例患者中检出动脉瘤34个，均行动脉瘤夹闭术并被术中证实。经MSCTA 检查检出动脉瘤33例，检查动脉瘤34个，其中大部分患者为单发（31例），多发1例，假阳性1例，为眼动脉起始部动脉瘤。DSA 检查32例患者中检出34个动脉瘤，但是其中单发30例，多发2例。与 DSA 作为金标准，评价 MSCTA 诊断颅内动脉瘤的敏感性、特异性及准确性分别为100．00％、87．50％、97．50％。MSCTA 检出瘤颈宽度1．85～4．33 mm，平均瘤颈宽度（3．65±1．85）mm；DSA 检出瘤颈宽度1．52～4．48 mm，平均瘤颈宽度（3．41±1．96）mm；经统计学分析发现两种方法检出的平均瘤颈宽度比较无统计学意义（t ＝0.78，P ＞0．05）。但是从检出的最小值来看，DSA 还是存在一定的优势。结论MSCTA 对颅内动脉瘤检查的灵敏度高，可以作为外科治疗或介入治疗颅内动脉瘤的筛选方法，但仍不能完全替代 DSA。

Objective To study the application value of multislice spiral CT angiography (MSCTA)in diag-nosis of intracranial aneurysms.Methods MSCTA was used to diagnose intracranial aneurysms in 40 patients with subarachnoid hemorrhage.Subtraction angiography digital (DSA)was used as the gold standard to evaluate the sensi-tivity,specificity and accuracy of MSCTA for diagnosis of intracranial aneurysms.Results In 40 patients,34 aneu-rysms were detected in 32 patients and they were all confirmed by incarceration of aneurysm.The aneurysms were de-tected in 33 cases by MSCTA,and the aneurysms were 34.Most of them were single (31 cases),1 case was multiple and 1 case was false positive.DSA was detected in 32 patients with 34 aneurysms,but single in 30 cases and multiple in 2 cases.DSA as the gold standard,the sensitivity,specificity and accuracy of MSCTA in diagnosis of intracranial aneurysms were 100%,87.50% and 97.50% respectively.MSCTA detected aneurysm neck width 1.85 -4.33mm, average aneurysm neck width was (3.65 ±1.85)mm.DSA detected aneurysm neck width 1.52 -4.48mm,average aneurysm neck width was (3.41 ±1.96)mm.The average tumor neck width detected by the two methods had no sta-tistically significant difference (t =0.78,P >0.05).But from the minimum of the detection,DSA still had certain ad-vantages.Conclusion The sensitivity of MSCTA for intracranial aneurysms was high.It can be used as a method for surgical treatment of intracranial aneurysms,but it still can not completely replace the DSA.
