【摘要】 本文收集经手术、脑血管造影等证实的脑动静脉畸形69例,CT诊断与手术病理、脑血管造影等符合率为92.7％。脑内隐匿性AVM诊断较为困难,讨论了隐匿性AVMCT表现的病理基础及鉴别诊断要点。有82.6％的病例临床诊断为其它疾病,l3％的病例CT平扫阴性,应引起重视。提出了双剂量增强在脑内AVMCT诊断中的应用。更多还原

【Abstract】 69 cases of cerebral arteriovenous malformation(AVM) were collected which were confirmed by operation and cerebral angiography. Out of them, 82.6% were clinically misdiagnosed and 13% were negative in conventional CT scanning. Coincideance rate of CT diagnosis with operation and angiography was 92.7%. It was difficnlt to diaguose the hidden cerebral AVM, which was discussed in pathological base and differentioal diagnosis. The author suggests that double dose enhancement should be used in diagnosis of AVM.更多还原
