Figure 2From: Multimodal noninvasive and invasive imaging of extracranial venous abnormalities indicative of CCSVI: Results of the PREMiSe pilot study Example of normal and abnormal flow morphology in internal jugular vein (IJV) on magnetic resonance venography (3D TRICKS and axial 2D TOF). Normal (A & B) flow morphology in both IJV (arrows). Abnormal (absent flow) (C & D) flow in the left internal jugular vein (arrow) with prominent collateral veins (dotted arrows).Back to article page
