Prevalence and malignancy risk of focal colorectal incidental uptake detected by (18)F-FDG-PET or PET/CT: a meta-analysis.

CIs represent a challenge for the clinicians: some of these findings are benign but the risk of malignancy in CIs might be significant. 1 As Fluorine-18-Fluorodeoxyglucose positron emission tomography or positron emission tomography/computed tomography ( 18 F-FDG-PET or PET/CT) are increasingly used, especially for oncologic patients, incidental uptake detected by these functional imaging methods are also increasing. 18 F-FDG-PET or PET/CT may sometimes reveal an unexpected area of increased radiopharmaceutical uptake within the large bowel in patients referred for other diseases and this finding is defined as CI. 1 , 2 Both focal, segmental and diffuse unexpected 18 F-FDG uptake in the large bowel were reported.
