摘　　要：目的探讨多回波采集重度T2*WI三维梯度回波序列(ESWAN)诊断颅内多发海绵状血管瘤(CA)的应用价值。材料与方法回顾性分析临床证实的47例颅内CA患者的MRI资料,比较ESWAN与常规MRI序列显示CA的敏感性和特异性。结果 47例中,ESWAN序列完全显示颅内CA的病灶,且具有影像的特征性的"铁环征、桑椹状"或完全低信号影,与其他常规MRI序列相比,病灶检出的差异有统计学意义(P<0.05)。结论 ESWAN显示CA较其他常规MRI序列有更高的敏感性和特异性,是诊断CA的最佳序列,应作为CA的常规检查序列。Objective：To evaluate the diagnostic value of enhanced gradient echo T2 ＊ weighted angiography（ESWAN） in multiple intracerebral cavernous angioma（CA）.Materials and methods：The MRI data of the 47 patients with intracerebral cavernous angioma were retrospectively analyzed.And the sensitivity and specificity of ESWAN were compared with conventional sequences of MRI.Results：In 47 patients,ESWAN showed all the lesions of intracerebral cavernous angioma,and typically showed the sample of popcorn,mulberry or fully hypointensity.The difference of detection among MRI sequences was statistically significant（P0.05）.Conclusion：ESWAN is the best sequence which has higher sensitivity and specificity than conventional MR images in the diagnosis of cavernous angioma.
