In this study, we have proposed measuring average CBF in a group of 140 patients and 26 normal controls. In the MS patient group, there appears to be a dependence of average CBF with total IJV flow. This result suggests that there is a link between total IJV flow and disrupted blood flow from the brain. Future research should be to validate this effect using perfusion weighted imaging to see if this is a global CBF deficit or has major local deficits as well.

Mr. David Utriainen presented for Mr. Yi Zhong on a study showing cerebral blood flow collected at the C2 and C6
levels for the IJV. Flow measurements were also performed and it was concluded that the IJV flow may be
considered a biomarker for stenosis.
