目的 探讨超声组织定征(UTC)对不同程度均匀性脂肪肝测量诊断的作用。方法 用传统均匀性脂肪肝的分级方法将脂肪肝分为 度、 度、 度三个等级,UTC视频法测量每一度脂肪肝患者二维超声图像的灰阶值。结果 脂肪肝级别愈高,则后方衰减愈明显,距离愈远衰减愈重。UTC视频法测出的肝脏声像图的灰阶值 度与 度从8cm处开始,在脂肪肝分级中的差异有统计学意义(P<0 .0 5 ) , 度与 度及 度与 度均从6 cm处开始有统计学意义(P<0 .0 5 )。结论 可用超声视频法这一无创性的UTC检查方法对均匀性脂肪肝的程度进行声像图测量诊断。
Objective To investigate the role of ultrasonic histology (UTC) in the diagnosis of fatty liver with different degrees of homogeneity. Methods The fatty liver was divided into three grades of degree, degree and degree by the method of traditional uniform fatty liver grading. The gray scale value of two-dimensional ultrasound images of each degree of fatty liver was measured by UTC video method. Results The higher the level of fatty liver, the more obvious attenuation of the rear, the farther away from the more attenuated. The grayscale value and degree of liver sound image obtained by UTC video method started from 8cm, there was significant difference in the classification of fatty liver (P <0.05), degree and degree and degree and degree From 6 cm at a statistically significant (P <0. 05). Conclusion Ultrasound video method, a noninvasive method of UTC, can be used to diagnose the extent of HFS.
