WebA small amount of diastolic flow reversal is physiologic. Holodiastolic flow reversal as in this image, however, is pathologic and an important qualitative sign of at least moderate aortic regurgitation. PW Doppler can be used to measure the regurgitant volume (RV AR) or regurgitant fraction (RF AR) of the AR jet. WebThe main findings on the hepatic duplex sonogram in the disease group were a decrease in the size of the antegrade systolic wave with a systolic/diastolic flow velocity ratio of less than 0.6 (n = 4) or reversal of the systolic wave (n = 10). In all volunteers, systolic flow was antegrade and the ratio was more than 0.6.
