This study demonstrates imaging with a radially undersampled 4D PC MR technique, PC VIPR, to view and measure flow within the cerebrospinal veins in a reproducible fashion. Volunteers were imaged at three stations to visualize the vasculature of the head, neck and chest. This study shows the feasibility of (1) duplicating flow measurements between scans, (2) the ability to show and measure venous reflux, and (3) the consistency of venous caliber assessments, including that of the azygous vein, by CE-MRA scoring.
