| MRV - Lateral View. MRV is used to evaluate for cerebral sinus thrombosis, which typically occurs in hypercoaguable states, including late in pregnancy and following delivery. In the lateral view, the largest sinus, the superior sagittal sinus is well seen, as is the straight sinus, vein of Galen and internal cerebral veins. However, the transverse and sigmoid sinuses overlap as do the internal jugular veins. |
