Abstract: Objective To explore the images of the internal cerebral vein(ICV) and its tributaries by the 2D time-of-flight(2D-TOF) magnetic resonance venography (MRV), quantitative and qualitative assessment by the GE advance Workstation,and construct the 3D map of ICV and its tributaries. Methods The images of ICV and its tributaries were got by the 2D-TOF MRV in sixtytwo normal volunteers,the quantitative and qualitative assessment were processed by the GE advance Workstation. Results Display rate of ICV was 100%,bilateral arrangement.Medial vein of lateral ventricle was 46.0%,the distance from the drainage point to the column of fornix was （23.09士1.96）mm，the angle with the internal cerebral vein was(119.9士12.8)°,diameter was（1.27士0.23）mm.Septal vein was 96.8%,diameter was （1.26士0.25）mm, thalamostriate vein was 70.2%，diameter was （1.33士0.16）mm，the angle between two veins in horizontal axis was （79.1±9.2）°.Supe
