Objective To investigate the value of quantitative ultrasound elastic parameters in OJ. Methods Patients with OJ who met the inclusion criteria (n=90) in our hospital between January 2014 and June 2015 were recruited. They were divided into severe OJ group (Group A), moderate OJ group (Group B)，and slight OJ group (Group C) according to total bilirubin. And 30 cases without clinical jaundice were selected as D group. The ％AREA、MEAN were compared and analyzed. ROC curves were drawn to evaluate the AUC, diagnostic threshold, sensitivity and specificity of OJ, slight, moderate or severe OJ. The correlation between %AREA, MEAN levels and total bilirubin was assessed with Pearson correlation analysis. Results Compared to Group with OJ(45.09±2.38), Group without OJ(43.04±1.86) showed significantly lower levels of ％AREA (t=8.74；P=0.000)．The threshold of ROC Curve with ％AREA in diagnosing OJ was 44.44 with the sensitivity of 58.9％，the specificity of 83.7％ and AUC of 0.729.Compared to Group with OJ(78.43±3.53), Group without OJ (84.75±3.53) showed significantly higher levels of MEAN (t=-8.56；P=0.000)．The threshold of ROC Curve with MEAN in diagnosing OJ was 81.04 with the sensitivity of 83.3％，the specificity of 78.9％ and AUC of 0.889. There was no significant difference in the level of %AREA and MEAN between A and B group. %AREA level was significantly positively correlated with total bilirubin level, and MEAN level was negatively correlated with total bilirubin level. The threshold of ROC Curve with %AREA in diagnosing slight OJ was 43.54 with the sensitivity of 65％，the specificity of 86.7％ and AUC of 0.811. And the threshold of ROC Curve with %AREA in diagnosing moderate and severe OJ was 47.21 with the sensitivity of 68％，the specificity of 92.5％ and AUC of 0.879.The threshold of ROC Curve with MEAN in diagnosing slight OJ was 83.07 with the sensitivity of 53.3％，the specificity of 90％ and AUC of 0.750. And the threshold of ROC Curve with MEAN in diagnosing moderate and severe OJ was79.95 with the sensitivity of 65％，the specificity of 98％ and AUC of 0.791. Conclusion Quantitative ultrasound elastic parameters can effectively identify OJ and degree of obstruction.
