摘要
笔者总结了经证实的１５例脊髓血管畸形的ＭＲＩ表现，发现有两种表现形式：局限性和非局限性。前者均位于髓内，病灶小，未见畸形血管，但有较特征的ＭＲＩ信号改变，血管造影亦无阳性发现。后者则以粗大迂曲的畸形血管为主要特征，血管造影有阳性发现。ＭＲＩ检查有助于发现隐匿性血管畸形，减少了血管造影的盲目性。对非隐匿性血管畸形，ＭＲＩ能清楚显示脊髓血管畸形的部位、与周围结构关系等，对诊断和治疗有很大帮助。
patients with proved arteriovenous malformations of spinal cord were analyzed.MRI manifestations could be divided into two groups:localized and non-localized.The localized formusually presented the following MRI signs:lesions confined in the spinal cord,small,with characteristicsignal intensity pattern but no discernible abnormal vessels.This form being angiographically occult,was known as occult vascular malformation(OVM).The non-Iocalized form was characterized by ab-normal largetortuous vessels and corresponding angiographic findings.At present,MRI is becoming avery useful and non-invasive method in the diagnosis and treatment of OVM and non-occult AVM ofthe spinal cord.
