title: Consistency analysis of contrast-enhanced ultrasound and contrast-enhanced CT in diagnosis of small hepatocellular carcinoma.
abstract: To compare the consistency of contrast-enhanced ultrasound (CEUS) and contrast-enhance CT (CECT) in diagnosis of 1~2 cm and 2.1~3 cm small hepatocellular carcinoma (HCC) and evaluate the value of CEUS in diagnosis of HCC.
  
  
  METHODS
  A total of 74 patients (89 lesions) with small HCC and cirrhosis background were retrospectively analyzed. All of the eighty-nine lesions were confirmed by histopathological examination of surgical samples or needle biopsy. All the cases were divided into 1~2 cm group and 2.1~3 cm group. The CEUS and CECT enhanced pattern and diagnosis results of the two groups were compared and the consistency between the two imaging methods were statistically analyzed.
  
  
  RESULTS
  In the diagnosis of 1.0-2.0 cm HCC, CEUS and CECT had a moderate consistency in arterial phase, CEUS showed a tolerable consistency with CECT in portal venous and delayphase. The two imaging methods have a better consistency for the diagnosis in 2.1-3.0 cm HCC.
  
  
  CONCLUSIONS
  CEUS can be used as a supplement to provide important diagnostic information in clinical practice when positive results or definite diagnoses cannot obtain.
