  • Image Result

    Example of invasive Doppler flow wire velocity waveforms in the mid renal artery. Peak systolic velocity here is 80 cm/s. End-diastolic velocity is 15 cm/s. This yields an RI of 81.

  • Image Result

    Scatter plot of renal index (RI) derived by catheter Doppler flow wire and renal duplex ultrasonography (RDUS). A robust correlation is seen, with r = 0.86 (95% CI, 0.73 to 0.93).
