You might want to contact Anne Musson at Dartmouth Hitchcock Medical Center.
They have an excellent criteria using PSV, EDV and velocity ratios used for
identifying percent stenosis greater than 50%. Using all of the above
parameters, stenosis have been broken down into 50-59%, 60-69%, 70-79% and
80-99%. Works very well for them.
Dr. Mark Fillinger published these results. Anne may be able to provide
Hope this helps.

Subject: Carotid Stenosis Criteria
Our lab is discussing new criteria for reading and categorizing stenosis in
extracranial studies (in effect velocity vs ICA/CCA ratios).
My medical director wanted to post this question: What criteria are other
labs using to identify 60% stenosis in the ICA, 70% stenosis, and 80%
stenosis? Any input would be greatly appreciated.
By the way, the lab is accredited and has been recently reaccredited...we
just have new readers wanting to bring in new diagnostic criterion.
