A 58-year-old man with rectal adenocarcinoma. Axial T2-weighted SPACE image (a), fused 18 F-FDG PET image and axial T2-weighted SPACE image (b) obtained by hybrid PET/MR showing FDG avid rectal wall thickening at the left lateral wall. SUVmax, SUVpeak, and SUVmean of the tumor were 8.14, 6.76, and 5.21, respectively. DWI (c) depicted the tumor as a high signal intensity lesion, and the corresponding ADC map (d) showed reduced ADC in the tumor (ADCmean was 1.04 × 10−3 mm2/s)
