Abstract: Objective To discuss the imaging features of dural arteriovenous fistula(DAVF).Methods The imaging features of DAVF patients after 2005 were analyzed retrospectively.Results Thirty-two cases suffering from DAVF were treated from 2005. CT and MRI examintionscould well show the intracranial lesions secondary to DAVF including the enlarged draining veins,hemorrhage, and narrow and occluded venous sinus. DSA could exactly show the orifices, feedingateries and draining veins of DAVF, and distribution of the intraranial blood flow, but not thecerebral parenchyma lesion secondry to of DAVF.Conclusion DSA is an ideal and reliable method for the diagnosis of DAVF. CT and MRI canprovide the useful information for the diagnosis of DAVF.
