WebFeb 18, 2024 · Recent publications suggest a link between ciliopathy and AIS. More specifically a modification of the cerebro-spinal fluid (CSF) flow by ciliary dysfunction could be at the origin of a scoliotic deformity. This study aims to compare the CSF flow measured by magnetic resonance imaging (MRI) in an AIS group and a control group.
