1. A system for fusing and synthesizing a plurality of medical images defined by a plurality of imaging parameters comprising: an image fusion processor that fuses a plurality of magnetic resonance imaging (MRI) datasets, wherein a first image dataset of the MRI datasets is defined by apparent diffusion coefficient (ADC) values and a second image dataset of the MRI datasets is defined by at least one parameter other than the ADC values; and wherein the image fusion processor generates a fused response image that visually displays a combination of image features generated by the ADC values combined with image features generated by the at least one parameter other than the ADC values.
