目的
评估三维 CT 血管造影 (CTA) 在颅内动脉瘤检测和表征方面的准确性，并帮助确定其作为无症状人群动脉瘤筛查测试的作用，以及作为蛛网膜下腔出血血管造影和未经治疗动脉瘤随访的辅助手段的作用。
方法
在一项双盲前瞻性研究中，对 80 名有症状的动脉瘤患者进行 3-D CTA 研究，分析了动脉瘤的存在和形态。血管造影或手术作为对照。
结果
63 名患者中发现了 94 个动脉瘤。 17 例血管造影呈阴性结果。3-D CTA 对所有动脉瘤、所有患者以及 5 毫米或更小的动脉瘤的敏感性和特异性分别为 90.4% 和 50%、98.4% 和 82.4%、78.8% 和 51.9%。
结论
三维 CTA 可能在普通人群无症状动脉瘤的无创筛查中发挥作用，但当从有症状患者获得的数据外推到患有较小动脉瘤的无症状人群时，建议谨慎。此外，3-D CTA 可作为血管造影的辅助手段，用于表征浆果动脉瘤和未治疗动脉瘤的随访。
PURPOSE
To assess the accuracy of three-dimensional CT angiography (CTA) in the detection and characterization of intracranial aneurysms and to help determine its role as a screening test for aneurysms in the asymptomatic population and as an adjunct to angiography in subarachnoid hemorrhages and in the follow-up of untreated aneurysms.
METHODS
In a blinded, prospective study, the 3-D CTA studies in 80 patients with symptomatic aneurysms were analyzed for the presence and morphology of aneurysms. Angiography or surgery acted as the control.
RESULTS
Ninety-four aneurysms were found in 63 patients. Negative findings at angiography were noted in 17. Sensitivity and specificity of 3-D CTA for all aneurysms, all patients, and aneurysms 5 mm or smaller were 90.4% and 50%, 98.4% and 82.4%, and 78.8% and 51.9%, respectively.
CONCLUSION
Three-dimensional CTA may have a role in noninvasive screening for asymptomatic aneurysms in the general population, but caution is advocated when data obtained from symptomatic patients are extrapolated to the asymptomatic population who harbor smaller aneurysms. Also, 3-D CTA may be useful as an adjunct to angiography in the characterization of berry aneurysms and in the follow-up of untreated aneurysms.
