1. A method of imaging a region of interest (“ROI”) including a breast having received a dose of radionuclide using an imaging system including at least two gamma detectors arranged in opposition with the ROI arranged therebetween, the method comprising the steps of: a) acquiring imaging data of the ROI using the at least two gamma detectors; b) segregating the imaging data into a plurality of subsets of data by using a relative energy associated with the imaging data with respect to a single photopeak; c) generating a plurality of images using the subsets of data, wherein the plurality of images include a primary image corresponding to subsets of data having energy including the single photopeak and multiple scatter images corresponding to subsets of data having energy below and not including the single photopeak; d) processing each of the plurality of images using energy information associated with each of the plurality of images; and e) combining the processed plurality of images to form a composite image of the ROI.
