摘    要:对经手术证实的20例脑动脉瘤的MRA和IA-DSA的影像进行了对照分析研究,经MRA检出19例(95%)动脉瘤,9例为10mm以下的动脉瘤,最小的4mm,与DSA检出率(19/20)相仿。MRA的定位符合率为84%,低于DSA(95%)。13/19例(68%)在MRA图像上能显示动脉瘤的瘤颈。作者认为MRA是一种新的非侵入性的血管影像方法,可作为脑动脉瘤高危病例的筛选检查,随着MRA技术的进一步完善,MRA有望在神经外科领域替代部分侵入性血管造影检查。

Abstract:We compared magnetic resonance angiography (MRA) and intra-arterial digital substraction anglography(IA-DSA ) in 20 cases with intracranial aneurysms. All cases were confirmed by operation. 13 of 14 (93% ) lesions were detected by MRA. The diameter of 9 aneurysms were less than 10mm, the slnallest one was 4mm, The size of the lesions were well corrected with IA-DSA. As colnpared with the relationship between the aneurysms and their parent vessels in MRA+IA-DSA, 9 of 13 lesions were well assessed by MRA. The location of the aneurysms also were studied and showed 10 of 13 (77 % ) aneurysms were precisely positioned by MRA, it was lower than IA-DSA (95% ). Therefore, authors conclude that MRA,as a new, noninvasive method of vascular irnaging, is a useful tool for screening in patients with high risk for intracranial aneurysm. And looking forward, with further improvement of MRA technique, it will replace part of regular invasive contrast angiography.
Keywords:intracramal aneurysm  magnetic resonance angiography  intra-arterial digital substraction angiography
