摘要
目的：探讨高分辨率磁共振成像（HRMRI）在大脑中动脉（MCA）狭窄或闭塞中的诊断价值。方法：47例缺血性脑血管病患者先后行HRMRI及DSA检查，以DSA为金标准，分析HRMRI对MCA狭窄的诊断价值。结果：47例患者有45支MCA图像质量符合要求。 HRMRI对狭窄程度的判定结果与DSA结果的符合率为82．22％（37/45），一致性较高（Kappa＝0．709，P＜0．001）。 HRMRI测得的狭窄率为0．72（0．60～0．86），DSA测得的狭窄率为0．68（0．57～0．82），二者差异无统计学意义（Z＝1．430，P＝0．150）。结论：HRMRI在评估MCA狭窄方面与DSA具有良好一致性。
Aim：To explore the diagnostic value of high-resolution MRI （ HRMRI） in evaluating middle cerebral ar-tery（ MCA） stenosis or occlusion .Methods： Forty-seven patients with ischemic cerebrovascular disease underwent both HRMRI and DSA examinations .Based on the results of DSA , the gold standard , the diagnostic value of HRMRI for detec-ting MCA stenosis or occlusion were analyzed .Results： Forty-five segments diagnosed by HRMRI were consistently with DSA.The rate of coincidence was 82.22%（37/45）.Two imaging modalities conformed well in evaluation of the degree of stenosis（Kappa=0.709,P〈0.001）.The MCA stenosis rates were 0.72（0.60-0.86） by HRMRI and 0.68（0.57-0.82） by DSA.There was no statistical difference in evaluating the stenosis rate by HRMRI or DSA （ Z=1.430, P=0.150）.Conclusion：In evaluating MCA stenosis or occlusion, HRMRI is well consistent with DSA.
