Figure 3: The left cavernosal artery spectral waveform of the same patient as in Figures 1 and 2 at 5-min postintracavernosal injection of prostaglandin E1 showing abrupt increase in both systolic and diastolic flow and low-resistance monophasic flow with peak systolic velocity of 24.96 cm/s. Note the end-diastolic velocity of cavernosal artery was 3.9cm/s
