超声影像对中心性肥胖人群非酒精性脂肪肝病变诊断的临床观察

Value of Ultrasonography in Diagnosis of Central Obesity Crowd with Non Alcohol Clinical Fatty Liver Disease

目的:探讨中心性肥胖人群非酒精性脂肪肝病变的声像图特点及临床诊断意义。材料与方法:仪器使用Philips-PH11型超声诊断仪,探头频率3.5-4.5 MHz,患者禁食禁水8h以上,对肝脏进行纵横及多切面扫查,观察其发生部位、大小、形态、内部及后方回声和周围血管的血流情况。结果:500例中心性肥胖受检者超声检查,诊断为非酒精性脂肪肝者共389例,其中,轻度脂肪肝186例,占47.82%;中度脂肪肝132例,占33.93%:重度脂肪肝54例,占13.88%;非均匀性脂肪肝17例,占4.37%。结论:超声扫描对中心性肥胖人群非酒精性脂肪肝病检出率高,对患者的早期诊断、早治疗有极其重要作用。

Purpose： To explore the value of ultrasonography in diagnosis of central obesity crowd of nonalcoholic fatty liver disease. Materials and Methods： Philips- PH11 ultrasonic diagnosis instrument was used in the research,the probe frequency was 3. 5- 4. 5 MHz,and the patients were fasted for 8h above,and scaned multi section of the liver position,size,shape,blood flow,rear echo and the surrounding blood vessels. Results： 500 cases of central obesity subjects ultrasonography,diagnosis of nonalcoholic fatty liver were 389 cases,among them,186 cases of low- grade fatty liver,accounting for47. 82%; 132 cases of moderate fatty liver,33. 93% ： severe fatty liver in 54 cases,accounting for 13. 88%; non- uniform fatty liver in 17 cases,accounting for 4. 37%. Conclusion： Ultrasonic scanning on central obesity crowd of nonalcoholic fatty liver disease has high detection rate,and was extremely important on aspect of early diagnosis as well as early treatment.
