Transverse dural sinuses: incidence of anatomical variants and flow artefacts with 2D time-of-flight MR venography at 1 Tesla


This study sought to identify imaging criteria useful in discriminating anatomical variants from thrombosis of the posterior intracranial venous system. A total of 102 patients underwent coronal unenhanced two-dimensional time-of-flight (2D ToF) magnetic resonance (MR) venography. Transverse sinus (TS) calibre and asymmetry were considered. Oval (O-FG) and… (More)
