The Diagnostic Performance of CT versus FDG PET-CT for the Detection of Recurrent Pancreatic Cancer: A Systematic Review and Meta-Analysis
ConclusionsAccording to the current literature, post-operative CT has a moderate diagnostic accuracy in the detection of recurrent disease. FDG PET-CT imaging could be of additional value when disease recurrence is suspected despite negative or equivocal CT findings. Nevertheless, evidence supporting radiologic surveillance after resection of PDAC is limited. Future prospective studies are needed to optimize surveillance strategies after resection of pancreatic cancer. (Source: European Journal of Radiology)
