Abstract: Objective To measure the sizes of the left and right internal jugular veins (IJV) and transverse sinuses (TS) with three dimensional contrast‐enhanced MRA(3D CE‐MRA) ,and discuss the correlation of cerebral venous sinus and IJV .Methods One hundred and ten patients without vasculopathy and blood flow abnormalities were selected for 3D CE‐MRA ,55 cases for each gender .The images were taken three‐dimensional reconstruction on work‐station by different software .The normal IJV and TS was measured and the statistical comparison between the bilateral IJV and TS was analyzed .Results (1)The inside diameter of IJV re‐duced in turn at the measurement point of J1 ,J2 and J3 .The internal diameter of the right side of IJV was broader than left one ,and there was significant difference between the size of left and right side (P<0 .05) in these measurements .The internal diameter of the right side of TS was broader than left one ,there was difference between the sizes of the left and right of TS (P<0 .05) .(2)The proportion of R>L ,R
