摘要：
A computer-based method is herein disclosed, allowing to differentiate automatically between two tissues of interest: an extrinsic and an intrinsic tissue, from a plurality of images, obtaining a quantitative assessment of each of said tissues without requiring the intervention of an expert. Said method involves the definition of a differentiation region in images obtained from a medical imaging acquisition device using a parametric contour, after which differentiation and quantification are carried out based on the photometric characteristics of the different tissues observed in images, evaluating the local neighborhood of each voxel belonging to the differentiation region previously defined in the plurality of images. The disclosed method increases to a great extent precision in differentiation and quantification of tissues, while the shown percentage error is considered tolerable for diagnostic purposes.
