A duplex exam of renal arteries was performed to rule out renal artery stenosis.\r<br>\r<br>Renal artery Doppler rules out renal artery stenosis.\r<br>\r<br>Color and pulsed Doppler as well as gray-scale imaging demonstrated normal blood flow in both kidneys. Acceleration times demonstrated normal renal arterial .\r<br>\r<br>Renal artery Doppler rules out renal artery stenosis.\r<br>\r<br>Color Doppler and pulsed Doppler demonstrate a stenotic portion of the renal artery. Parvus tardus is evident in Doppler wave=forms in the renal parechyma.
