Dural venous drainage was classified based on torcular Herophili anatomy by using 4D flow MR imaging–derived angiograms and magnitude images. Subjects were scanned in a 3T clinical MR imaging system. 4D flow MR imaging enabled noninvasive characterization of dural sinus anatomy and mapping of relative pressure differences.DAVFdural arteriovenous fistulaTStransverse sinus ER -
