FIG 3. Measurement of flow changes within neck arteries is demonstrated. A, Section positioning (line) was performed on CE-MRA data such that the section was approximately perpendicular to the vessels and just distal or proximal to the stenosis (arrow). Qflow measurements were then performed at this site immediately before (B) and following (C) stent placement. Shown are the magnitude (left) and phase (right) images demonstrating the reproducibility of the scan plane and the increase in flow in the stented artery (arrows).
