This purpose of the study is to evaluate the diagnostic performance of FDG-PET/CT and DWI with conventional MRI in peritoneal metastases detection and to assess the correlation between SUV and ADC measured by FDG-PET/CT and DWI with conventional MRI, respectively, in peritoneal metastases. The prospective study recruited patients with suspected peritoneal metastases, and the acquired FDG-PET/CT and DWI/MRI images were reviewed independently by two radiologists. Results showed no significant differences between FDG-PET/CT and DWI/MRI in peritoneal metastases detection, and statistically significant inverse correlation was found between SUV and ADC.
