High field MRI and histopathology correlation results for rectal cancer tissue specimen 3. The MRI images shown are (a) A0, (b) ADC map, and (c) direction encoded colour fractional anisotropy (FA) map. The annotated regions are diffusion tensor image and histopathology are: A cancer B desmoplasia C muscularis propria inner circular layer D muscularis propria outer longitudinal layer and E heterogeneous regions of granulation tissue and inflammation. The direction encoded colour FA map was the best image to distinguish the different tissue regions of interest; muscularis propria was clearly distinguished from cancer on this image.
