摘　　要：目的研究磁共振成像(MRI)结合磁共振血管成像(MRA)诊断脑血管畸形的价值。方法回顾性分析2017年8月到2019年8月到我院就诊疑似脑血管畸形患者86例,其中经过确诊80例,所有患者均进行MRI及MRA检测。以手术病理结果为"金标准",统计MRI、MRA及两者结合对脑血管畸形的诊断效能,统计MRI、MRA及两者结合对不同部位病变的检出率,统计MRI、MRA及两者结合对不同类型病变的检出率,统计MRI、MRA及两者结合检测的海绵血管瘤病灶面积。结果 MRA结合MRI的诊断准确性高于MRI、MRA,差异有统计学意义(P<0.05);三种检测方式诊断灵敏性、特异性无统计学差异(P>0.05);三种检测方式对不同部位病变的检出率无明显差异,差异无统计学意义(P>0.05);三种检测方式对不同分型病变的检出率无明显差异,差异无统计学意义(P>0.05);MRI结合MRA检测海绵状血管瘤的病灶面积大于单一检测,差异有统计学意义(P<0.05)。结论 MRI结合MRA诊断脑血管畸形诊断效能更好。Objective To study diagnostic value of magnetic resonance imaging(MRI)combined with magnetic resonance angiography(MRA)for cerebral vascular malformation(CVM).Methods A retrospective analysis was performed on 86 patients suspected with CVM who were treated in our hospital from August 2017 to August 2019.Among them,there were 80 cases confirmed.All patients underwent M RI and MRA.Taking su rgical pathological results as"golden standard",diagnostic efficiency of MRI,MRA and their combination for CVM was statistically analyzed.The detection rates of MRI,MRA,and their combination for lesions at different sites were statistically analyzed.The detection rates of MRI,MRA,and their combination for different lesion types were statistically analyzed.The lesion areas of cavernous angioma detected by MRI,MRA and their combination were statistically analyzed.Results The diagnostic accuracy of MRA combined with MRI was higher than that of MRI and MRA alone(P<0.05).There was no significant difference in sensitivity or specificity among the three kinds of detection methods(P>0.05).There was no significa nt difference in detection rate of lesions at diffe rent sites among the three kinds of detection methods(P>0.05).There was no significant difference in detection rate of different lesion types among the three kinds of detection methods(P>0.05).The lesion area of cavernous angioma detected by MRI combined with MRA was larger than that of single detection(P<0.05).Conclusion The diagnostic efficiency of MRI combined with MRA is better on CVM.
