Routine bolus chase peripheral MRA was performed on 48 patients followed by 2D cine PC flow measurements for each leg obtained above and below the SFA lesion. Flow pattern, flow volume and velocity data were also obtained from 9 healthy volunteers. The severity of SFA disease was graded as normal, no significant lesion (< 50%), moderate-to-severe stenosis ( 50%) or occlusion and correlated with flow data. Two variables showed statistically significant positive correlation with the severity of arterial disease, including existence of peak delay (r = 0.65, p < 0.001) and peak velocity ratio (r = 0.31, p < 0.001).
