    A 66-year-old male patient with severe stenosis of the proximal segment of the right main renal artery. A, The renal peak systolic velocity (PSV) at the stenotic site = 246 cm/s (positive); the renal-aortic ratio = 2.1 (false negative). B, The PSV in the distal segment of the right main renal artery = 121 cm/s; the renal-renal ratio = 2 (positive). C, Spectral analysis of the interlobar artery shows that its PSV = 44 cm/s and the renal-interlobar ratio = 5.6 (positive). No obvious tardus-parvus waveform is observed. D, Arteriography shows a severe stenosis (arrow) in the proximal segment of the right renal artery afterwards.
