Pre- and Post-Treatment MR Imaging and Single Photon Emission CT in Patients with Dural Arteriovenous Fistulas and Retrograde Leptomeningeal Venous Drainage

摘要

BACKGROUND AND PURPOSE: Dural arteriovenous fistulas (DAVFs) with disturbed regional cerebral blood flow (rCBF) include retrograde leptomeningeal venous drainage (RLVD). We examined rCBF disturbances in patients with DAVFs by studying MR imaging and single photon emission CT (SPECT) changes before and after treatment.
