Claim 21:
22. Method for analyzing MRI of an organ of a subject, comprising:
operating an MRI scanner to generate a first and a second MRI scan respectively at the beginning and end of a predetermined time interval post contrast administration, wherein the beginning of said predetermined time interval is at least five minutes and no more than ten minutes post contrast injection, and wherein the end of said predetermined time interval is at least twenty minutes after the beginning of said predetermined time interval;
forming, by an image processor, a subtraction map from said first and said second MRI scans by analyzing said scans to distinguish between two primary populations, a slow population, in which contrast clearance from the tissue is slower than contrast accumulation, and a fast population in which clearance is faster than accumulation;
applying registration between corresponding MRI images, smoothing a translation matrix resulting from said registration using circular smearing, and interpolating to obtain translation values per pixel; and
converting said scans to a displayed subtraction map on which distributions of said two primary populations are distinguished wherein a distribution of said fast population is corresponds to a tumoral tissue region and a distribution of said slow population corresponds to a non-tumoral tissue region.
