Comparative study of real-time tissue elastography and FibroScan in evaluation of hepatic fibrosis

To comparatively analyze the application value of realtime tissue elastography（RTE） and Fi- broScan in assessment of hepatic fibrosis. Methods One hundred and twentyone patients infected with chronic HBV were ex- amined by percutaneous hepatic biopsy, then they were graded into S0-S4, and simultaneously conducted with RTE and FibroScan. The liver fibrosis index （LF Index） calculated by 9 variables achieved with RTE in multivariate regression analysis was taken as RTE index. The elastic stiffness value （Stiffness） achieved in 10 successful FibroScan examinations was taken as FibroScan index. Results With S grading increased, the mean value of LF Index and Stiffness had a trend of gradual increasing. The correlation coefficient of RTE and FibroScan indexes with the fibrosis grading was 0. 667 and 0. 664. Taking S2 and S3 as a dividing line, the area under ROC curve of LF Index and Stiffness were 0. 886, 0. 877 and 0. 917, 0. 873 ,respectively. Conclu- sion RTE and FibroScan have similar role in determining hepatic fibrosis.
