MRI and MR Angiography Findings to Differentiate Jugular Venous Reflux From Cavernous Dural Arteriovenous Fistula

摘要

OBJECTIVE. Both jugular venous reflux (JVR) and cavernous dural arteriovenous fistula (DAVF) manifest as abnormal venous signal intensities on time-of-flight (TOF) MR angiography (MRA). We investigated brain MRI and MRA findings that might differentiate JVR from cavernous DAVF.
