目的:探讨CT对早期肝硬化诊断的价值。方法:将48例CT诊断早期肝炎后肝硬化组及96例慢性肝炎分轻、中、重组行肝脏穿刺活检。活检标本分别进行苏木素(HE)、网状纤维Gomori法、范基森(VG)、结缔组织Masson三色法染色检查,将病理检查结果与临床及CT影像特征相对照。结果:CT检查提示早期肝硬化病理检查结果仅6例符合(6/48,12.5%)。慢性肝炎轻、中度与病理诊断符合率各为85.7%(36/42)、75%(36/48)。但两组不符合部分仅为轻-中度之间的交叉。慢性肝炎重度与病理诊断符合率100%(6/6)。CT肝脏形态缩小的影像特征,与肝组织病理学纤维化指征符合率达100%。与无肝缩小征象组对照,无一例符合。结论:CT肝脏形态缩小是早期肝硬化的较可靠诊断依据。慢性肝炎临床诊断与病理符合率高,如非必要,可免将肝活检用于慢性肝炎的常规诊断检查。
Objective: To investigate the value of CT in the diagnosis of early cirrhosis. Methods: Forty-eight CT patients with posthepatitic cirrhosis and 96 chronic hepatitis were divided into liver, liver, and liver biopsy. Biopsy specimens were stained with hematoxylin (HE), reticular fibers Gomori, VG, and Masson trichrome staining respectively, and the pathological findings were compared with clinical and CT features. Results: CT examination showed that only 6 cases of pathological examination of early cirrhosis meet the criteria (6 / 48,12.5%). The coincidence rates of mild, moderate and pathological diagnosis of chronic hepatitis were 85.7% (36/42) and 75% (36/48) respectively. However, the two groups of nonconformities only cross between light and medium. The coincidence rate of chronic hepatitis and pathological diagnosis was 100% (6/6). CT liver morphology reduced image features, and pathological liver fibrosis indicators in line with 100%. No signs of liver shrinkage with the control group, no case of compliance. Conclusion: CT liver morphology reduction is more reliable diagnosis of early liver cirrhosis. Chronic hepatitis clinical diagnosis and pathology in line with the high rate, if necessary, may be exempt from liver biopsy for routine diagnosis of chronic hepatitis.
