(Aside, from Cece: I am not currently sure about the role of MRV in research or clinical diagnosis. If we see some data showing that the MRV agrees with what is found on venogram, that would be something to go on.)

page 9 is labelled: "Jetting through a stuck valve?" but I am not sure we are seeing anything there! Any better eyes than mine disagree?
page 10: "4D: New directions in Flow?" ... interesting!
page 12: MRV does nicely show the sinus abnormality
page 14: "to treat or not to treat?"
page 15: "Two functioning IJVs: what would be the consequence of treating one of these and causing a complete obstruction?"

Is he suggesting that the flow could be normal even if there is a severe structural abnormality such as a 50% stenosis? Or am I misreading that?Flow and Structure: two possible guides for treatment
If there is a severe structure abnormailty such as a stenosis great than 50% or higher then we might be tempted to treat it.
However, what if the flow is in fact normal?
Is it worth the risk of damaging two healthy veins that are doing their job in carrying the flow even though other aspects of the system may be compromised (such as the vertebral plexus, externals, vertebrals, etc.)?
