If you are speaking of extemity arteries the main parameter I've used is PSV. Visual in grey scale and color, areas of apparent plaque do a proximal PSV, PSV at site of maximum stenosis then document turbulent flow distal. Criteria uaually is doubling of PSV equals approximate 50%, tripling of PSV equals aprx 75% stenosis.

Hi all,

I have a question for those who do native arterial imaging.  What
hemodynamic parameters do you routinely measure?  We get a peak systolic
and end diastolic velocity but not too much else.  We will also measure
volume flow.  Depending on the circumstances, we also record the vessel
diameter.  Does anyone measure anything else, like PI, RI, and so on?

Thanks
Ann Marie
