目的评价相位对比法磁共振血流成像(phase-contrast magnetic resonance angiography ,PC-MRA)、CTA、3D-DSA对脑血管疾病诊断的准确性.方法 70例怀疑有脑血管疾病者均行PC-MRA、CTA及3D-DSA检查,比较3种方法对脑血管疾病的敏感性.结果 70例患者诊断出有脑血管病变的51例,检出动脉瘤患者33例,发现瘤体36个,检出动静脉畸形18例.PC-MRA检出动脉瘤33个,敏感性为91.67%,检出动静脉畸形17例,敏感性为94.44%.CTA检出动脉瘤34个,动静脉畸形16例,敏感性分别为94.44%和88.89%.3D-DSA检出动脉瘤35个,敏感性97.22%,动静脉畸形18例,敏感性100%.三者在对动脉瘤、动静脉畸形敏感性上比较均无显著性差异(P>0.05). 结论 PC-MRA,CTA和3D-DSA在诊断脑血管畸形方面无明显差异 .

Objective To evaluate the accuracy and clinical efficacy of low field phase-contrast magnetic resonance angiography(PC-MRA),CTA and 3D-DSA in the diagnosis of cerebrovascular disease.Methods 70 patients with clinically suspected cerebrovascular diseases were examined with PC-MRA,CTA and 3D-DSA.The sensitivity in detecting the cerebrovascular disease with these three methods were compared.Results Fifty-one patients were detected with cerebrovascular diseases in seventy patients by three imaging methods,including 36 aneurysms in 33 cases and 18 arteriovenous amlformations.33,34 and 35 aneurysms,17,16 and 18 arteriovenous malformations were detected by PC-MRA , CTA and 3D-DSA respectively , the sensitivity were 91.67% and 94.44%,94.44% and 88.89%,97.22% and 100% respectively.There were no significant difference in the sensitivity of detecting aneurysm and arteriovenous malformation between these three imaging methods(P＞0.05).Conclusion PC-MRA,CTA and 3D-DSA are no of difference in diagnosis of cerebrovascular malformation.
