WebOblique Approach. Angling 45 degrees to right renal artery.In most individuals, the renal arteries arise from the abdominal aorta immediately distal to the origin of the SMA.By moving the probe to the right of midline and angling toward the patient’s left, an acceptable Doppler angle of 45-60 degrees is achieved. Anterior Approach. WebA. peak velocity B. mean velocity C. resistive index D. Doppler shift B. Color doppler shows the mean flow velocity of rbc while PW doppler displays the peak velocity of rbc. If the transmitted frequency is 5MHz and the reflected frequency 4.9975 MHz, how will the Doppler shift be displayed?
