color bruit

A Doppler reading obtained near the renal artery origin shows velocities over 600 cm/s in systole and over 300 cm/s in diastole consistent with a high grade stenosis. Note that rolling the patient into a decubitus position and angling the probe back toward the aorta have purposefully decreased the angulation of the renal artery. The arrows are pointing to a bruit that is evident on the spectral display.
