title: [Comparison analysis of multi-modalities images in 158 patients with hepatic tumor].
abstract: OBJECTIVE
  To compare and analyze the positron emission tomography (PET) images with other multi-modalities in the diagnosis of hepatic tumors.
  
  
  METHODS
  A total of 158 patients undergoing (18)F fluorodeoxyglucose (FDG)-PET were enrolled along with another 55 cases with (11)C acetate-PET (AC-PET) imaging within 1 week. The pathological results were taken as the golden criteria. Tumor marker, contrast ultrasound, computed tomography (CT) and magnetic resonance imaging (MRI) results were collected.SPSS 19.0 was used for statistical analysis.
  
  
  RESULTS
  Contrast MRI, ultrasound and CT were more effective than PET in the differential diagnosis of hepatic tumor.FDG-PET showed a better accuracy in the diagnosis of intrahepatic cholangiocarcinomas, metastasis and rare primary hepatic carcinoma. AC-PET was a good complementary method to FDG-PET. Consideration of tumor size, amount, laboratory results and history could improve the diagnostic accuracy of PET and enhanced CT.
  
  
  CONCLUSIONS
  PET must be combined with other image modalities to differentiate hepatic tumors more effectively and accurately.
