The mean ATP SI(%) values at the tumor site of the largest cross-section of rectal cancer are closely related to its pathological stage, and they are statistically significant in pathological T stage and N stage(pT stage: p=0.008; pN Stage: p=0.000).
Figure2. Magnetic resonance images showing a 57-year-old male patient with rectal cancer. The tumor is isointense on T1-weighted MR image, mildly hyperintense on T2-weighted MR image, hyperintense on DWI (b = 1000 s/mm2) , and isointense on ATP image (d).
