then into each Jugular vein......nothing to do with the head or Brain....Dr Haacke has written a program to measure Iron deposits in the Brain via an MRI and SWI ....perhaps this is confusing you.
That is not quite accurate, ace. actually we can opacify and see the dural sinuses which are channels that drain the blood of the brain and pass it on, out of the skull into the jugular and vertebral veins.
There is some controversy about whether ccsvi affects the dural sinuses. Sometimes it appears on MRV that the sinuses are narrowed or occluded. This needs to be clarified and understood. And stenosis of jugular veins is reported to be associated with dural sinus thrombosis, leading to mental confusion and memory problems, loss of balance, and fatigue that resolves after the thrombus is dissolved and the jugular stenosis is angioplastied.
