Example of internal jugular vein pathology on cine phase-contrast MRI study. The regions of interest (ROIs) outlined are the internal jugular veins. These ROIs were used to measure the flow through these vessels. An example showing the flow quantification magnitude image in stenotic (A) and normal IJV (B) and the flow quantification on phase images of the same IJVs (C and D). Graph showing the differences in velocity between stenotic and non stenotic IJV (E).
