Abstract: A system and method of non-invasive diagnosis of a condition in a subject may include obtaining, from a medical scanning device, a three-dimensional (3D) scan of the subject, said scan comprising a plurality of quantitative or semi-quantitative voxel values; segmenting the scan, to obtain a segmented region of interest (ROI) of the subject; performing a singular value decomposition (SVD) of the ROI, to determine at least one axis of the ROI in the SVD space; and analyzing the voxel values along the at least one axis, to diagnose a condition of the subject. Analysis of the voxel values may include calculating a quantitative function of voxel values along the at least one axis; comparing the calculated quantitative function to a reference quantitative function; and diagnosing or predicting a condition of the subject, based on the comparison.
