title: [Comparison of treatment response in primary hepatocellular carcinomas with contrast-enhanced ultrasonography and contrast-enhanced helical CT].
abstract: OBJECTIVE
  To investigate the value of contrast-enhanced ultra sonography for non-surgical treatment response in hepatocellular carcinomas.
  
  
  METHODS
  Non-surgical therapies were performed on 56 patients (64 liver neoplasms) who were diagnosed by ultrasonography-guided biopsy before the therapy. Contrast-enhanced ultrasonography(CEUS) and contrast-enhanced helical CT were performed to assess the treatment response.
  
  
  RESULTS
  Forty-six of the 64 lesions were not enhanced with CEUS.Partial enhancement was demonstrated in the other 18 lesions. Forty-eight of the 64 lesions were not enhanced with contrast-enhanced helical CT. Partial enhancement were demonstrated in the other 16 lesions.The sensitivity, specificity, and accuracy were 94.4%, 97.8%, and 96.9% for CEUS and 83.3%, 97.8%, and 93.8% for contrast-enhanced helical CT (P>0.05).
  
  
  CONCLUSIONS
  CEUS is a good method in assessing the non-surgical treatment response in hepatocellular carcinomas and is more sensitive and useful than contrast-enhanced helical CT in assessing the treatment response of transcatheter hepatic arterial chemoembolization.
