title: [Comparison of FibroTouch and FibroScan for the assessment of fibrosis in chronic hepatitis B patients].
abstract: OBJECTIVE
  To perform a comparative assessment of the performance of FibroTouch and FibroScan in patients with hepatitis B.
  
  
  METHODS
  A total of 211 patients with hepatitis B, including cases of chronic hepatitis B (CHB) and of compensated cirrhosis, were enrolled for study between June and November of 2013. The patients underwent FibroScan testing (group 1) and FibroTouch testing (group 3), after which the operator examined a time motion ultrasound image from the FibroScan test and located a specific liver portion for focused FibroTouch testing (group 2). The consistency between the two tests' results was investigated by Pearson's correlation analysis, and the difference of liver stiffness between CHB patients and compensated cirrhosis patients was investigated by the two independent samples t-test or Mann-Whitney U test.
  
  
  RESULTS
  The values of liver stiffness were 5.30 (4.30,8.65) in group 1,6.10 (4.70,8.90) in group 2, and 5.70 (4.50, 8.00) in group 3 (all P < 0.05); the Pearson correlation coefficients were all more than 0.8 (P < 0.05) and there was no statistically significant difference found between the results from FibroScan and FibroTouch.The values of liver stiffness were significantly different between the CHB patients and the compensated cirrhosis patients (P < 0.05). The rates of successful detection were 100% for FibroTouch and 97% for FibroScan.
  
  
  CONCLUSIONS
  FibroTouch and FibroScan have good consistency in the evaluation of the degree of liver fibrosis. FibroTouch has a higher rate of successful detection than FibroScan.
