Lorraine, For greater than 60%, we use >180 cm/sec with post stenotic
     turbulence and a dampened waveform distally, acceleration time >100ms. Most
     stenoses exhibit velocities much higher than 180 and we have had a few
     minimally diseased vessels with PSV in the 160-200 range) so be sure to
     document all the other things. We have had excellent success when all
     criteria are used.

       Will some of you share the diagnostic criteria you are
       currently utilizing to
       document presence and severity of renal artery stenosis?
       Thank you.
