Fig. 5From: Validation of high temporal resolution spiral phase velocity mapping of temporal patterns of left and right coronary artery blood flow against Doppler guidewireCMR measurement of the ratio of peak diastolic velocity to peak systolic velocity (PDV/PSV) plotted against Doppler values in 8 right coronary arteries (a) and 14 left anterior descending arteries (b). (One LAD artery was excluded as it had no systolic peak)Back to article page
