Figure 1 Corrected carotid flow time was calculated by the measurement of interval between the start of systolic upstroke and the dicrotic notch of the spectral Doppler waveform: a) systole time; b) cycle time. Carotid blood flow was calculated by the measurement of velocity time integral tracing of the c) spectral Doppler signal and d) carotid diameter.
