Abstract:
1. A method for processing MRT data of a brain of a patient, wherein three-dimensional MRT data resolved in voxels of the brain of the patient and brains of a normative database of a plurality of neurologically healthy human individuals are available, comprising the steps of: segmenting the MRT data of the brain of the patient for each voxel into portions of grey substance, white substance and liquor by way of a classification algorithm, transforming the data to be compared with corresponding data of the normative database into a standardized stereotactic space, resulting in one or more normalized tissue maps that contain proportions determined by the classification algorithm, wherein the transformation occurs before, after or synchronous with segmentation, and subjecting the tissue map or tissue maps of the brain of the patient to a voxel-wise statistical comparison with correspondingly normalized and segmented data of the normative database, wherein the voxel-wise statistical comparison of the tissue map, or tissue maps, is a morphometric comparison, wherein statistically significant voxels in the tissue map, or tissue maps, of the brain of the patient are identified that belong to a region dominated by the white substance that contains more grey substance than should be expected from the normative database, or that belong to a region dominated by the grey substance that contains more white substance than would be expected from the normative database.
