A patient with refractory hypertension is referred for a renal artery duplex exam. The peak systolic velocity (PSV) in the suprarenal aorta is 80 cm/s. The highest PSV obtained in the proximal right renal artery is 300 cm/s. What is the calculated Renal-Aortic Ratio (RAR), and what is the most likely interpretation?

RAR is 3.75, suggestive of a hemodynamically significant stenosis (>60%). RAR is 0.27, which is within normal limits. RAR is 3.75, which is within normal limits. RAR is 2.50, suggestive of a non-hemodynamically significant stenosis (<50%).

Correct Answer:

RAR is 3.75, suggestive of a hemodynamically significant stenosis (>60%).
