The role of magnetic resonance imaging in assessing venous vascular abnormalities in the head and neck: a demonstration of cerebrospinal venous insufficiency in a subset of multiple sclerosis patients
"Our own work over four independent sites shows good agreement, indicating that there is a high incidence of stenosis and structural venous abnormalities in the MS population and that this change results in reduced outflow of the IJVs and increased collateralization of venous return to the heart compared to healthy controls."
Tweeted from Dr. Paolo Zamboni: "Vascular abnormalities are more common in MS. Results of 559 MR studies."
