Objective To investigate the clinical value of 18F-FDG PET/CT image in assisting CT-guided puncture of pancreatic tumor.Methods One hundred and thirteen patients with pancreatic tumors were selected and then divided into 18 F-FDG PET/CT image-assisted CT-guided group(abbreviation 18F-FDG PET/CT-assisted group)(n=54)and CT-guided group(n=59)according to the different guided puncture methods.The diagnostic efficacy and safety of the two guided puncture biopsy methods were analyzed and compared.Results All patients successfully completed the biopsy.The accuracy(the agreement rate between pathological diagnosis and final clinical diagnosis),sensitivity,and complication rate of the 18F-FDG PET/CT-assisted group were 96.30％(52/54),96.15％(50/52),and 3.70％(2/54);and those of the CT-guided group were 84.75％(50/59),83.64％(46/55),and 15.25％(9/59).Ultimately,it was found that the 18F-FDG PET/CT-assisted group performed better in terms of accuracy and complications than CT-guided group,and the differences were statistically significant(x2=4.280 9,P=0.038 5;x2=5.211 4,P=0.022 4).No serious complications such as hemorrhage,abdominal infection,pancreatic fistula,intestinal fistula and so on occurred in all patients.Conclusion 18F-FDG PET/CT image in assisting CT-guided pancreatic tumor puncture possesses more efficient,precise,and safe characteristics,which is the innovation and expansion of traditional CT image-guided puncture biopsy.However,there is still improvement room in terms of economy and feasibility.
