Blood flow measurement was performed in 58 kidneys of healthy persons. Detection rate, maximum flow velocity (Vmax), pulsatility index (PI) and resistive index (RI) were measured at main renal artery, segmental artery, interlobar artery and interlobular artery with 2 D-Doppler ultrasound machines. Detection rate was highest at interlobar artery. Vmax and PI tended to fall down with arterial branching. Interlobular artery was usually not visualized by color flow mapping, but sometimes well visualized using Acuson machines. Additional measurement of interlobar and interlobular arteries were performed in such 15 cases, and the result was essentially equal to the above mentioned study.
