|---|---|
| The cerebellum is known to be a prevalent site of MS pathology but is currently under-investigated due to small size and complex anatomy. Recent technical advances, including the development of 7T MRI-scanners and motion-compensation algorithms to reduce the effect of patient movement, now allow the investigation of cerebellar cortical volume, cortical thickness and quantitative MRI characteristics, such as T1 and susceptibility values, as well as regional functional changes. Our first main objective is to detect and characterize structural abnormalities (small lesions, paramagnetic rim lesions, microstructural changes and tissue specific atrophy) in pwMS using high-resolution anatomical data (7T MRI). To this end, with 7T MRI we will acquire submillimetre structural images of the entire brain (0.5mm3) including T1-weighted MRI, quantitative susceptibility and diffusion weighted imaging. Structural data will be compared between pwMS and HC. Within subjects, already collected 3T data in the same patient will be used to compare patterns of cerebellar damage to assess the added value of detecting lesions at 7T compared to 3T. Our second main objective is to improve our understanding of the functional 7T MRI changes within the cerebellum, as this is a particularly understudied field of research in MS. Cerebellar regional and subject specific functional activation and connectivity will be investigated during movements and at rest. To this end, we will acquire high-resolution functional 7T MRI-data during visually guided force matching23 of hand and foot and during rest. The task and resting-state functional MRI (fMRI) data will be compared between pwMS and HC. | — |

| Measure | Time frame |
|---|---|
| Our secondary objective is to investigate the relations between structural changes, functional disturbances (activation levels during movements and RS connectivity strength at rest) and clinical disability within the cerebellum. Structure-function relationships will be examined within both pwMS as well as HC. Within the MS group, the relation between MRI measures and clinical disability will be investigated. | — |
