摘　　要：目的探讨硬脑膜动静脉瘘(DAVF)的CT、MRI、DSA影像学特点。方法2016年1月—2019年7月间回顾性分析法对30例经DSA证实的DAVF的临床病史及影像学资料,比较患者的临床表现分析,CT、MR扫描影像学与DSA影像学扫描图像进行对比。结果CT平扫15例脑出血,CTA诊断为动静脉瘘8例,MR诊断动静脉瘘13例。DSA清晰显示瘘口、供血血管及静脉引流血管30例。结论CT表现脑表面的多发迂曲增粗血管影及部分间接征象;MRI表现为颅内或颅颈交界区的流空血管影;DSA能够清晰显示动静脉瘘瘘口部位、供血动脉、静脉引流情况,有利于手术提供准确指引,制定更完善的治疗方案。CT和MRI可以为DAVF的诊断提供帮助,但是确诊以DSA为金标准。Objective To explore the CT,MRI and DSA imaging features of dural arteriovenous fistula(DAVF).Methods From January 2016 to July 2019 The clinical history and imaging data of 30 servings of DAVF confirmed by DSA were retrospectively analyzed.The clinical manifestations of patients were compared,CT,MR scanning imaging and DSA imaging scanning images were compared.Results CT scan of 15 cases of cerebral hemorrhage,CTA diagnosis of 8 cases of arteriovenous fistula,MR diagnosis of 13 cases of arteriovenous fistula.DSA clearly showed 30 cases of fistula,blood supply vessels and venous drainage vessels.Conclusion CT showed multiple tortuous thickened blood vessel shadows on the surface of the brain and some indirect signs;MRI showed empty blood vessel shadows in the intracranial or craniocervical junction area;DSA can clearly show the fistula of arteriovenous fistula,blood supply artery,and venous drainage In order to provide accurate guidance for surgery and develop a more complete treatment plan.CT and MRI can help the diagnosis of DAVF,but DSA is the gold standard for diagnosis.
