超声弹性成像评分在脂肪肝分度中的应用价值

The application value of score by ultrasound elastography at fatty liver graduation

目的:探讨超声弹性成像评分方法在脂肪肝分度中的应用价值。方法:选择脂肪肝患者轻度、中度、重度3组合计77例,设正常对照组30例,所有患者常规超声扫查后,使用超声弹性成像技术进行扫查,并按照超声弹性成像评分标准给患者评分。结果:①超声弹性成像评分随脂肪肝程度的加重而增加。②超声弹性成像评分方法与传统超声方法在脂肪肝分度上有较高的一致性(Kappa值=0.833)。③超声弹性成像评价脂肪肝的敏感性、特异性分别为96.1%、93.3%。结论:超声弹性成像技术可以作为较客观评价脂肪肝分度的辅助检查方法。

Objective： The aim of this study was to investigate the application value of score by ultrasound elastography in grading fatty liver. Methods： Seventy-seven patients with fatty liver were enrolled, and 30 patients with proven healthy livers were used as control group. After all patients with conventional ultrasound scanning, and following ultrasound elastography scan, we scored patients with fatty liver in accordance with ultrasound elastography score criteria. Results： There was a high consistency between ultrasound elastography score and traditional ultrasound score （Kappa value=0.833）. The sensitivity, specificity of fatty liver evaluated by ultrasound elastography were 96.1%, 93.3% respectively. Conclusion： Ultrasound elasticity imaging technique can be used as a more objective auxiliary examination method in grading fatty liver.
