This study aims to detect cortical lesions in MS patients. High resolution MTR scans (0.5mm isotropic, as well as 0.35mm in plane resolution) have been acquired at 7T using a novel imaging sequence. The MTR contrast has been compared between white matter and grey matter, showing a greater grey matter (GM) / white matter (WM) contrast to noise ratio at 7T, providing a good delineation of WM and GM lesions at high resolution with the MTR contrast. The sequence is being used to study changes in the cortex of MS patients.
