Fig. 2

An example of manual segmentation of MRI in the primary tumor of rectal cancer. a T2W maximum cross-sectional view, manually sketched T2WI-ROI (green intra-line region) and its histogram of primary tumors in patients with stage T3 rectal cancer. b The same slice DWI image from the same patient, the manually sketched DWI-ROI (red intra-line area), and its histogram. c The T2-map-ROI (red mosaic region) and its histogram of T2-map were obtained by mapping DWI ROI to T2WI. d The ADC-ROI (magenta mosaic region) and its histogram of the ADC diagram were obtained by mapping DWI ROI to the ADC graph
