声速匹配技术在大鼠肝脏脂肪评价中的应用
The application of sound speed correction technique in the evaluation of liver fat of rat
摘要
Abstract
Objective:To explore the relationship between the fatty liver of different levels and sound velocity, and discuss the feasibility of sound speed correction technique for the grading diagnosis of fatty liver.Methods: 80 SD rats were selected and divided into control group (n=20) and observation group (n=60). Zone speed index (ZSI) was measured and pathological analysis was carried out at different feeding weeks. Depended on the pathological analysis, the observation group was further divided into mild fatty liver group, moderate fatty liver group and severe fatty liver group, and the ZSI value among different groups was statistically analyzed. Results: The ZSI value of the control group was 58.40±2.04, and the ZSI values in mild group, moderate group and severe group were 45.74±6.07, 30.25±7.59 and 6.14±12.31, respectively. And the differences among control group, moderate group and severe group were statistically significant (t=8.892,t=7.075,t=6.889;P<0.05).Conclusion: The sound speed correction technique can be used to classify SD rats with fatty liver.关键词
