Clinical impact of fluorodeoxyglucose-positron emission tomography scan/computed tomography in comparison with computed tomography on the detection of colorectal cancer recurrence

Background and aims Early detection is an essential prognostic factor in colorectal cancer (CRC) recurrence. Our aim was to evaluate diagnostic performances of 18F-fluorodeoxyglucose-positron emission tomography (18F-FDG-PET)/computed tomography (CT) as compared with CT in the detection of CRC recurrence. Methods Data of patients with suspected CRC recurrence and in whom both FDG-PET/CT and CT were performed were analyzed. All detected lesions...
