Assessment of incidental focal colorectal uptake by analysis of fluorine-18 fluorodeoxyglucose positron emission tomography parameters

Figure 2 Cases with premalignant and benign incidental focal colorectal fluorine-18 fluorodeoxyglucose uptake. A: Focal uptake (black arrow) in the lower abdomen on the maximum intensity projection (MIP) image of a 41-year-old woman diagnosed with stomach cancer; B: Axial view showing a hypermetabolic rectal lesion (white arrow, SUVmax 10.1) diagnosed as rectal villous adenoma; C: Focal uptake (black arrow) in the right lower abdomen on the MIP image of a 42-year-old man diagnosed with stomach cancer; D: Axial view showing hypermetabolism (white arrow, maximum standardized uptake value 8.6) with a final colonoscopy report of “No remarkable mucosal lesion”.
