Claim 32:
33. Apparatus for operating MRI, comprising:
an MRI Scanner configured for performing an MRI scan using a 3D MRI pulse sequence;
an input for receiving first and second MRI scans of an organ of a subject respectively at the beginning and end of a predetermined time interval post contrast administration from said MRI scanner;
an image processor having a circuit configured for forming 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
an output 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 corresponds to a tumoral tissue region and a distribution of said slow population corresponds to a non-tumoral tissue region;
wherein said control is configured to carry out said first scan and said second scan such that said predetermined time interval is at least twenty minutes;
the apparatus being used for analysis of extra-cranial tumors.
