This study aimed to compare the value of fluorine-18 fibroblast activation protein-specific inhibitor (F-18-FAPI-42) and fluorine-18 fluorodeoxyglucose (F-18-FDG) positron emission tomography/computed tomography (PET/CT) for detecting PM of colorectal cancer and to guide clinical decision-making. Methods: Forty-eight patients with PM who underwent both F-18-FAPI-42 and F-18-FDG PET/CT examinations were studied. The maximum standardized uptake value (SUV max), tumor-to-background ratios (TBRs) and peritoneal cancer index (PCI) of the PM were compared between the two imaging techniques. The intraclass correlation coefficient (ICC) was used to compare the consistency between the PET/CT PCI score and the intraoperative PCI. A receiver-operating characteristic curve was us |
