- W2364357777 abstract "Objective To explore the diagnostic value on the dural arteriovenous fistula (DAVF) with the 3T three-dimensional time of flight magnetic resonance angiography(3D-TOF-MRA). Methods The MRI、MRA and DSA images were retrospectively compared and analyzed in 18 patients with DAVF.Results The most common site of DAVF occured in the fossa(15/18,9 cases in tentorial,4 cases in sigmoid sinus and transverse sinus,1 case respectively in confluence sinuum and jugular foramen area),2 cases in parietal lobe and 1 case in cavernous sinus.The most common clinical manifestations were intracranial hypertension(8 cases ) and epilepsy(4 cases ). Mixed signals with brain hemorrhage(9/18) were dearly seen,and other lesions such as peripheral vascular flow void signal,cerebral edema and brain atrophy could be depicited on MRI.3D-TOF-MRA could show feeding artery from the internal external carotid,vertebral basilar artery blood supply to participate in common(13/18cases),6 cases of increased blood concentration is consistent with DSA findings of retrograde cortical vein(CVR) drainage.Conclusion 3T 3D-TOF-MRA combination with conventional MR imaging can accurately determine the lesion site,feeding artery, cortical venous drainage and clearly show the secondary intracranial DAVF change,and make up a comprehensive evaluation on the DAVF." @default.
