应用超声组织定征视频法评价脂肪肝程度

目的探讨超声组织定征视频法(UTC)衡量均匀性脂肪肝程度的价值,以期确定一个脂肪肝定量诊断方法。方法 90例脂肪肝患者和30例正常对照纳入研究,以CT脂肪肝定量为参照标准,将脂肪肝分为轻、中、重三个程度;同期进行超声定量分析,测定二维肝脏图像的近场、中场、远场和胆囊的回声强度(Echo Intensity,EI)值,并测定肝肾回声强度之比值。结果脂肪肝的肝脏近、中场回声强度及肝肾回声强度比值明显高于正常对照组,而肝脏的远场回声强度值明显低于正常对照组,且随脂肪肝程度加重,差异越显著(P<0.05)。胆囊回声强度在中、重度脂肪肝中明显高于对照组(P<0.05),而轻度脂肪肝中无明显差异。肝脏和胆囊回声强度及肝肾回声强度比值在3个脂肪肝组间两两比较均有统计学意义(P<0.05)。结论超声组织定征视频法可以用于脂肪肝的诊断和程度确定,是另一种脂肪肝量化诊断方法。

Evaluating fatty liver of the degree by ultrasonic tissue characterization

【Objective】To investigate the value of patients with Uniformity of fatty liver by ultrasonic tissue characterization Quantitative Analysis,in order to explore a new way for a quantitative diagnosis of fatty liver.【Methods】90 patients with fatty liver and 30 healthy people were involved in our study.According to the CT quantity,we can divide fatty liver disease into mild,moderate and severe three levels.At the same time,we using the ultrasound Echo Intensity to measure the two-dimensional ultrasongraphy of the liver in the near,middle and far field,the gallbladder and the EI ratio of the liver and kidney.【Results】Compared with normal control group,the liver EI value of the near,middle field and the EI ratio of the liver and kidney in patients with fatty liver were all showed was significantly higher,but the liver EI value of the far field in patients with fatty liver were showed significantly reduced,Moreover,the patients with heavier pathological damage,the difference showed much more significantly(P<0.05).The EI value of gallbladder in middle and severe groups were both reached the significantly higher when compared with normal control group(P<0.05),while in the mild group showed no statistical difference,and The liver EI value of the near,middle,far field,the EI value of gallbladder and the EI ratio of the liver and kidney of all three groups had a significant difference respectively when compared to each other(P<0.05).【Conclusion】Ultrasonic tissue characterization Quantitative Analysis has a clinical utility value both in diagnose and degree differentiate patients with fatty liver,it is a new way for fatty liver quantitative diagnosis.
