The AT measures 0.11 sec. A color Doppler image of the stenotic left renal artery origin is seen in image .

The Doppler waveform obtained from the segmental renal arteries within the right kidney shows a tardus parvus shape with absence of the ESP .

post stenotic turbulance

Image shows a spectral waveform obtained in the area of poststenotic turbulence just beyond the maximal area of stenosis. The velocity is lower at 317 cm/s and the waveform profile is irregular due to the turbulent flow.

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.

color bruit

Image A is a color Doppler image of a stenotic right renal artery origin. A color bruit is seen in the tissue surrounding the area of the post stenotic turbulence. The presence of the bruit can help to identify the location of the stenosis and increase diagnostic confidence.
