    Validation of peak systolic velocity (PSV) ≥180 cm/s as indicator of renal artery restenosis. The horizontal dashed line indicates PSV of 180 cm/s, and the vertical dashed line indicates angiography-defined stenosis of 60%. In our own institutional cohort, significant agreement was observed between PSV ≥180 cm/s and angiographic stenosis ≥60% (κ = 0.6; P = .05).
