Comparison of quantitative indexes of different groups (a) shows the comparison of SNR values of three groups at different ROI. (b) Shows the comparison of CNR values of three groups at different ROI. (c) Shows the SNR elevation of group B and group C at different ROI. (d) Shows the CNR elevation of group B and group C at different ROI. AA: abdominal aorta, CFA: common femoral artery, PA: popliteal artery; ATA: anterior tibial artery, PTA: posterior tibial artery, FA: fibular artery, DPA: dorsalis pedis artery; SNR, signal-to-noise ratio; CNR, contrast-to-noise ratio; *P < 0.05 for comparison of groups A and B; #P < 0.05 for comparison of groups A and C; &P < 0.05 for comparison of groups B and C.
