Abstract

Purpose: This study sought to identify imaging criteria useful in discriminating anatomical variants from thrombosis of the posterior intracranial venous system. Materials and methods: 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 linear (L-FG) flow gaps were recorded. Several slices of the 2D ToF sequence were applied perpendicularly to the TS within each FG to avoid in-plane saturation. Results: Mean calibre of the right TS was significantly greater than the contralateral sinus (6.5 mm±1.84 vs 5.1 mm±1.72). Right and left dominance was observed in 61% and 17% of cases, respectively. The mean right-left TS diameter was 5.77 mm. Among 204 TS, 44 L-FG and 42 O-FG were observed. Partial L-FG (
