Claim 21:
22. Method for analyzing MRI of an organ of a subject, comprising:
operating an MRI scanner to generate a first MRI scan at a beginning of a predetermined time interval, said beginning being at least three minutes and no more than twenty minutes post contrast administration,
operating an MRI scanner to generate a second MRI scan at an end of said predetermined time interval, 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; 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;
wherein the method comprises carrying out registration between corresponding MRI scans, and wherein the method used for differentiating tumor from treatment effects.
