Figure 1 Magnetic resonance (MRI) scans of a 57-year-old man with rectal cancer. A thickened rectal wall on (A) axial and (B) sagittal T2-weighted image (long arrows). High signal on (C) diffusion-weighted image b=1000 s/mm2 and low signal on (D) corresponding apparent diffusion coefficient (ADC) map indicates the presence of water diffusion restriction, the feature of malignancy (short arrows). (D) Region of interest (ROI) of about 1 cm2 is placed within the borders of the tumor on the ADC map (circle). Measurement of mean ADC value and in-ROI ADC standard deviation.
