Abstract:
Objective To compare diagnostic value of ~(18)F-fluoredeoxyglucose (FDG) PET/CT with contrast-enhanced CT in detecting primary hepatic carcinoma and postoperative recurrence.Methods Twenty-five cases of primary hepatic carcinoma or postoperative recurrent tumor underwent whole-body ~(18)F-FDG PET/CT and contrast-enhanced CT within one week's interval.They were retrospectively reviewed and the difierences between these two modalities were investigated.Results Of these 25 cases,there were 13 cases with primary hepatocellular carcinoma.1 case with intrahepatic cholangiocarcinoma and 11 cases with postoperative recurrence.The sensitivity of 18 F-FDG PET/CT and contrast-enhanced CT in diagnosing primary hepatic carcinoma was 78.6%(11/14) and 92.9%(13/14),and sensitivity in diagnosing postoperative recurrent was 100.0%(11/11) and 63.6%(7/11) respectively.Conclusion Contrast-enhanced CT may have a slight advantage over PET/CT in detecting primary hepatic carcinoma,but ~(18)F-FDG PET/CT combined with contrast-enhanced CT has even greater accuracy.Meanwhile,~(18)F-FDG PET/CT has better diagnostic accuracy in detection of postoperative recurrent tumor.
