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.
