目的探讨双源CT血管造影(dual-source CT angiography,DSCTA)对颅内动脉瘤的诊断价值.方法收集95例蛛网膜下腔出血(subarachnoid hemorrhage,SAH)患者的DSCTA和数字减影血管造影(digital subtraction angiogaphy,DSA)资料,回顾性分析二者检出颅内动脉瘤并描述相关形态特征的效能.结果 DSCTA在88例SAH患者中检出动脉瘤117个.2例疑有动脉瘤,5例未检出动脉瘤,对这些病例行DSA复查,4例确诊动脉瘤,3例未检出动脉瘤.以DSA结果为金标准,DSCTA检诊颅内动脉瘤的特异性为100％,敏感性为96.7％,准确性为96.8％.颅内动脉瘤体积越大,DSCTA诊断的敏感性越高.即便对于微小动脉瘤,DSCTA诊断的敏感性亦可达90％以上.此外,DSCTA对动脉瘤最大径和瘤颈宽度的测量结果与DSA基本一致.结论 DSCTA是一种无创、快速、可靠、有效的方法,能准确提供手术所需的影像学资料.DSCTA诊断动脉瘤的特异性和敏感性与DSA基本相同,在颅内动脉瘤的急诊手术时较DSA更具优越性.

Objective To evaluate the diagnostic value of dual-source CT angiography (DSCTA) for intracranial aneurysms.Methods The data of DSCTA and digital subtraction angiography (DSA) were collected from 95 patients with subarachnoid hemorrhage (SAH).The efficacies of detection and description of morphologic features of intracranial aneurysms were analyzed retrospectively.Results A total of 117 aneurysms in 88 patients were detected with DSCTA.Two patients were suspected of having aneurysms,and no aneurysrms were detected in 5 patients.These patients were reexamined with DSA,4 were diagnosed as having aneurysm,and the aneurysms were not detected in 3 patients.DSA results were considered as gold standard,the specificity,sensitivity and accuracy of DSCTA for the detection of intracranial aneurysms were 100％,96.7％and 96.8％,respectively.The larger volume of intracranial aneurysm was,the higher the sensitivity of DSCTA diagnosis would be.Even for small aneurysms,the sensitivity of DSCTA diagnose was more than 90％.In addition,tmeasurement results of the maximum diameter and neck width of aneurysms measured by DSCTA were almost consistent with DSA.Condclusions SCTA is a non-invasive,quick,reliable,and effective method,and can provide accurate imaging information for surgery.The specificity and sensitivity of the diagnosis of aneurysms with DSCTA are almost the same with DSA.It has more advantages than DSA in the emergency operation of intracranial aneurysms.
