MRV – Dural Sinuses and Veins |
|
The MRV shows a venogram in the lateral projection demonstrating the dural sinuses and some of the cerebral veins. The superior sagittal sinus runs on the superior aspect of the falx, curves around the posterior parietal region and joins the straight sinus, and transverse sinus to enter the torcular herophili in occipital region. It receives between 10-15 superior cerebral veins. The inferior sagittal sinus is a much smaller vessel and drains into the straight sinus. The sigmoid sinus drains into the internal jugular vein (not shown) The vein of Galen receives the internal cerebral vein and the basal vein of Rosenthal.
