RESUMEN
Objective To investigate the feasibility of VTQ value of spleen in noninvasive assessment of staging of liver fibrosis in patients with hepatitis B.Methods VTQ values of spleen were measured in 56 patients with hepatitis B by using ARFI technique and liver biopsy was performed.The patients were then grouped according to the stages of liver fibrosis stage.The results were analyzed by the intergroup comparison,Pearson Correlation analysis,and receiver operating characteristic curve (ROC curve).Results There was positive association of the VTQ value with the stages of liver fibrosis,whose correlation coefficient was 0.83 (P ＜ 0.05);There was no significant difference between the spleen VTQ value and the liver fibrosis S1 and SO (P ＞ 0.05),whereas there were significant differences among other groups (P ＜ 0.05).The area under the ROC curve was 0.95,the cut-off value was 2.79m/s,and the specificity and sensitivity were 81.8％ and 91.7％ respectively.Conclusions The VTQ value measured by ARFI technique has a better value in noninvasive diagnosis of stages of hepatitis B liver fibrosis.
