if they identified 3/5 criteria, then there is enough evidence that CCSVI is present.
with respect to the discussion above and the time and thoroughness of the study, it depends on what you are doing the study for and how it will affect you decsion making.
for me, i do not believe the US study can exclude the presence of CCSVI. so, i primarly use a pre procedure US to evaluate the jugular veins looking for their presence, size, retrograde flow, webs, valve function etc. this study also functions as a great baseline for doing followup. this study can be done in 15-20 minutes and gives me the information i need/want prior to the venogram.
imaging of the DCV's has been dropped from the standard criteria. this is not to say it is not useful. and it may play an important role in identifying venous problems that exist within the cranial vault and be useful to follow intracranial venoplasties if there is role/utility/safety in performing them.
