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.
