Hepatic echo patterns and "right lobe to left lobe longitudinal diameter ratio" were compared in age- and sex-matched 100 normal subjects and 76 patients with diffuse liver diseases (38 cirrhotics and 38 noncirrhotics) in a prospective sonographic study. Various echo patterns, assigned to cirrhotic livers (bright liver, micronodulation, beam attenuation), could not differentiate cirrhosis from other diffuse liver diseases. In cirrhotic livers, the right lobe manifested a significant shrinkage, while the left lobe exhibited almost no alteration. Considering the right to left lobe ratio of 1.30 as a discriminatory value, the cirrhosis could be diagnosed with a sensitivity of 74%, a specificity of 100%, and an accuracy of 93%; the sensitivity rates were seen to be higher in postnecrotic cirrhosis than in alcoholic cirrhosis.
在一项前瞻性超声研究中，对100名年龄和性别匹配的正常受试者以及76名患有弥漫性肝病的患者（38名肝硬化患者和38名非肝硬化患者）的肝脏回声模式和“右叶与左叶纵向直径比”进行了比较。分配给肝硬化肝脏的各种回声模式（肝脏明亮、微结节、波束衰减）无法区分肝硬化与其他弥漫性肝病。在肝硬化肝脏中，右叶明显萎缩，而左叶几乎没有变化。将右叶与左叶的比例1.30作为判别值，可以诊断肝硬化，其敏感性为74%，特异性为100%，准确性为93%；坏死性肝硬化的敏感性高于酒精性肝硬化。
