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.
