This study evaluated the performance of 18fluorodeoxyglucose positron-emission tomography (FDG-PET)/computed tomography (CT) in detection of PC from CRC and correlated the most metabolically active quadrant with the most affected peritoneal area determined during surgery. Patients and Methods: This retrospective study compared the performance of FDG-PET/CT for PC diagnosis in 26 patients with CRC with histopathologically-confirmed PC with a control group of 26 patients. An FDG-PET/CT score established for each patient diagnosed with PC was compared with the peritoneal cancer index (PCI) performed during surgery. Results: The sensitivity and specificity of FDG-PET/CT for PC detection were 85% (22/26) and 88% (23/26), respectively. The most scored quadrant by FDG-PET/CT corresponded to the most scored quadrant at surgery in 77.3%. Conclusion: FDG-PET/CT may represent a useful tool for evaluating response to neoadjuvant chemotherapy in patients with PC of CRC origin. ER -
