摘　　要：目的探讨DSA、CTA与MRA在脑动脉瘤诊断中的应用价值。方法选取37例因蛛网膜下腔出血及有相关临床表现的高度可疑患者，男23例，女14例。37例均进行了DSA、CTA、MRA检查并与介入治疗和手术治疗结果进行对照。所有图像均经2位放射科医生进行双盲法分析评价。结果37例患者发现了45个动脉瘤，其中5例为多发病灶，1例直径为2mm的前交通支动脉瘤（3种方法均未检出）。DSA检出44个；CTA检出40个，漏诊5个；MRA检出37个，漏诊8个，其中还检出1例假阳性。结论CTA及MRA对脑动脉瘤的诊断能力与DSA在灵敏性与准确性上相当，且兼具无创性的优点，可作为首选检查方法。Objective To explore the value of digital substraction angiography （ DSA ）, computerized tomography angiography （ CTA ）, and magnetic resonance angiography （ MRA ） in the diagnosis of cerebral aneurysms. Methods 37 with subarachnoid hemorrhage （ SAH ） or suspected SAH due to related manifestations and related manifestation that mostly suspected to be SAH, 23 males and 14 females, were included in this study. DSA, CTA, and MRA were performed and the findings were compared with the outcomes of interventional therapy or surgery. All the images were separately analyzed by two radiologists. Results Forty-five aneurysms were found, five of which were multiple aneurysms, and one anterior communicating artery aneurysm 2 mm in diameter was not detectable by the three methods. 44 aneurysms were determined by DSA, 40 by CTA, and 5 were missed; 37 aneurysms were detectable by MRA, 8 were missed, and one was false positive. Conclusions CTA and MRA are similar to DSA in the sensitivity and accuracy of detecting cerebral aneurysms. They are non-invasive and can be used as the first choice of procedure for cerebral aneurysms.
