To verify the value of ultrasound (US) in the diagnosis of cirrhosis, the ratio of transverse caudate lobe width to right lobe width (C/RL) was determined with US in 25 healthy subjects and 156 consecutive patients with either histologically proved acute viral, chronic persistent, or chronic active hepatitis or cirrhosis. The C/RL ratio had a sensitivity of 43%, a specificity of 100%, and an accuracy of 79% in cirrhosis. The sensitivity was very low in alcoholic cirrhosis, low in cryptogenic cirrhosis, and high in hepatitis B virus related cirrhosis. In spite of its fairly low overall sensitivity, the C/RL ratio is a useful measurement in assessing chronic liver disease because of its high specificity in cirrhosis.
为验证超声（US）在肝硬化诊断中的价值，对25名健康受试者以及156例经组织学证实患有急性病毒性肝炎、慢性持续性肝炎、慢性活动性肝炎或肝硬化的连续患者进行了超声检查，测定了尾状叶横径与右叶横径之比（C/RL）。C/RL比值对肝硬化的敏感性为43%，特异性为100%，准确性为79%。该比值在酒精性肝硬化中的敏感性非常低，在隐源性肝硬化中较低，而在乙型肝炎病毒相关性肝硬化中较高。尽管总体敏感性相当低，但由于C/RL比值在肝硬化中具有高特异性，所以它是评估慢性肝病的一项有用指标。
