To assess the performance of FLAG and RSE NMR angiography 22 aortoiliac (A1) and 22 femoropopliteal (FP) angiograms in 11 healthy males, mean age 38 ± 7.6 years, were acquired. The image quality was graded in a blinded fashion by two independent readers. The readers grades were not statistically different ( K = 0.5696). The representation of diagnostic images was 6/ 11 FLAG and 8/ 11 RSE A1 as well as 8/ 11 FLAG and 8/ 11 RSE FP. On back‐to‐back comparison six RSE A1 and seven RSE FP were graded bettcr than their FLAG counterparts. Although these differences did not achieve a statistical significance RSE NMR angiography provided consistently better images and appears preferable for imaging of the peripheral vascular system in normal subjects. © 1990 Academic Press, Inc.
