The diagnostic performance of 18F-FDG PET/CT, CT and MRI in the treatment evaluation of ablation therapy for colorectal liver metastases: A systematic review and meta-analysis

18F-FDG PET/(CT) yields a higher sensitivity for detecting DP after ablation therapy compared with CT and has a comparably high specificity. These findings indicate that the use of 18F-FDG PET(/CT) in this setting particularly allows for minimization of the false-negative rate compared with CT without compromising the low false-positive rate.
