"CONCLUSION:
Cerebral CT venography is superior to MR venography in the
identification of cerebral veins and dural sinuses and is at least
equivalent in the diagnosis of dural sinus thrombosis. CT venography is a
viable alternative to MR venography in the examination of patients with
suspected dural sinus thrombosis."
This is discussing the
sinuses and cerebral veins, in or near the skull, which are not the
veins of most interest in CCSVI. The jugulars are in the neck and the
area of the valves, where maybe 75% of the issues are, are down at the
base of the neck near the collarbone.
Doppler ultrasound has been
the noninvasive screening tool of choice, followed by MRV, with CT not
being mentioned by the leading investigators. Invasive screening tool of
choice may be venogram plus intravascular ultrasound.
Hope this is helpful. I feel like I should add something critical of CCSVI since this is the critical thread. Hmmm.

However both valves appear malformed.
There is evidence of pooling of blood seen at the lower segments bilaterally with significant flow resistance.
This would seem to be indicative of CCSVI.
You don't know for sure until you have the minimally invasive
procedure done. According to Dr. Dake's research, the MRV correlated to
what was found on venogram 80% of the time which means 20% of the time
it didn't. The venogram was thought to be the standard or the correct
one, not the MRV, in the 20% where they differed.
