Attenuation of colonic tumorigenesis as shown by positron emission tomography (PET) imaging. A: A schematic diagram shows the PET imaging procedures with live mice. B: Representative mouse images captured by PET-computed tomography (CT) scanning in each group. The color code bar represents fluorodeoxyglucose (FDG) signal intensity. The abdominal regions are indicated with red boxes. C: Standardized uptake values of FDG signal in the whole mouse colon in different groups. n = 5 to 6 for each group (B and C). ^∗P < 0.05. AOM, azoxymethane; DSS, dextran sulfate sodium; L. reuteri, Lactobacillus reuteri; MRS, deMan, Rogosa, Sharpe; PBS, phosphate-buffered saline.
