When
compared to white matter or gray matter, the involvement of the cerebrospinal
fluid (CSF) in the Multiple Sclerosis (MS) disease has scarcely been explored
until now and typically a lumbar puncture is required. We investigate the
flow properties of the CSF in the aqueduct of Sylvius and how they relate to
other MS disease metrics, by using non-invasive MRI in a pilot study with MS
patients and healthy controls. An objective flow quantification technique
using automatic segmentation of the aqueduct was developed and was validated
on a flow phantom and scan-rescanning 4 subjects within a week.
