目的：寻找能直观、真实地反映肝脏质地的检查方法。材料和方法：对５０例正常肝、５０例典型肝硬化及５０例心衰所致的典型淤血肝在心脏搏动力作用下的声像图进行对照研究。结果：正常肝脏在Ｍ型ＲＶ－ＬＬ切面肝压迹出现，波型与心脏搏动形式一致，两者幅深差绝对值＜２ｍｍ；肝硬化肝压迹消失或明显低于心搏幅度，两者幅度差绝对值＞４ｍｍ；淤血肝肝压迹出现变浅，但波形与心脏搏动形式一致两者幅深差绝对值＜２ｍｍ与正常比较无差异。结论：实时Ｍ／Ｂ型声像图能够直观、真实地反映出整个／局部肝脏质地状况。
Objective: To find the test method that can directly and truly reflect the liver texture. MATERIAL AND METHODS: Contrast study was made on the sonograms of typical congestion liver caused by 50 cases of normal liver, 50 cases of typical cirrhosis and 50 cases of heart failure. Results: Normal liver appeared on the M-type RV-LL hepatic indentation with the same pattern of heart beat, the absolute value of the difference was <2mm; the liver cirrhosis disappeared or significantly lower than the amplitude of heart beat, both The absolute value of amplitude difference> 4mm; congestion of liver liver marks appear shallow, but the waveform and heart beat form the absolute difference between the two amplitude <2mm no difference compared with the normal. Conclusion: Real-time M / B type sonography can intuitively and truly reflect the whole / partial liver texture.
