摘要
报道了６４例脑动静脉畸型和８例脑海绵状血管瘤的ＭＲＩ表现，并对ＭＲＩ、ＣＴ及脑血管造影在脑血管畸形诊断中的应用价值进行了对比分析。６４例脑动静脉畸形的ＭＲＩ均见到典型征象──流空信号簇。２９例见到粗大的供应动脉或／和引流静脉，１４例见到扩大的静脉窦。结果表明，ＭＲＩ对于脑动静脉畸形及其并发症的诊断优于ＣＴ，并可弥补脑血管造影的不足。ＭＲＩ与ＣＴ的联合应用对脑海绵状血管瘤的定性诊断很有意义。
MRI findings of intracranial arteriovenous malformations(AVMs)in 64 patients and cavernous hemangioma in 8 patients were reported and compared with those of CT and cerebral angiog-raphy,Typical sign of signal void at the AVM area was found on MRI. Twenty-nine cases demon-strated dilated feeding arteries and /or draining veins and in 14 cases enlarged venous sinus was seen. The results indicated that MRI is more sensitive and specific in the detection of intracranial AVM and its complications than CT and provide additional informations to cerebral angiography.A combined applica-tion of MRI and CT is very useful in the diagnosis of cavernous hemangioma.
