Abstract:
Objective To study 18F-FDG PET/CT and enhanced CT in the evaluation of resectability of pancreatic cancer.Methods The 18F-FDG PET/CT and enhanced CT images of patients with pancreatic cancer were analyzed and the results in assessing resectability were compared.The diagnosis of pancreatic cancer and resectability were confirmed by intraoperative findings and histopathology.Results 31 patients with pancreatic cancer underwent surgery.Complete resection of the tumor was successfully carried out in 18 patients.Palliative operations were performed in the remaining 13 patients because the tumors were unresectable.The sensitivity,specificity and accuracy for unresectabilitywere 94.4％,15.3％,61.2％ using enhanced CT,94.4％,38.4％,70.9％ using 18F-FDG PET/CT,and 88.8％,53.8％,71.3％ using a combination of these two examinations,respectively.There was no significant difference between enhanced CT and 18 F-FDG PET/CT.A combination of these two examinations was significantly better than either one of these examinations.Conclusions Either enhanced CT or 18F-FDG PET/CT was useful,and they complemented each other in assessing resectability of pancreatic tumor.A combination of these two examinations was more evaluable than either one of these examinations.
