It has been suggested that multiple sclerosis may be
associated with changes in the brain's draining veins.
In this study we investigated the existence of those
changes using time resolved MR angiography in three
different groups: patients with MS, their healthy
siblings and unrelated controls. We analyzed the
cerebral circulation times for the three groups and did
not find significant differences between the different
groups (p>0.2). The results obtained suggests that
drainage abnormalities are not characteristic for MS.
