Detailing intra-lesional venous lumen shrinking in multiple sclerosis investigated by sFLAIR MRI at 7-T - "This study found the inside diameter of veins within MS lesions does not change significantly (the research hypothesis looked for decreases in diameter), with 50% of lesions showing reductions in diameter and the other 50% presumably showing no change or increases. This finding is consistent with CCSVI, where intraluminal defects could narrow veins, but increased intracranial venous pressure could enlarge other veins."

Intra-lesional venous lumen shrinking detectable by MRI was suggested as an in vivo marker of inflammation in multiple sclerosis (MS). In our study mean diameters of pre-, post- and intra-lesional venous sections were determined in 49 patients with MS or clinically isolated syndrome (CIS) using a pi…
