| To investigate the causes of these diseases, MRI scans will be performed on patients with normal and those with CSF circulation disorders to collect information on CSF physiology. We will analyze CSF circulation information in each region of the cerebrospinal cord cavity using MRI in patients with normal and in patients with CSF circulation disorders by applying the improved time-slip method sequence to CSF, and develop temporal sequences with up-date.In order to clarify how CSF moves within the ventricles in response to head movement, we attempted to optimize its MRI visualization. | — |
