超声积分法对肝硬化的早期诊断

To investigate the imaging feature of early cirrhosis. 102 patients with chronic hepatitis were enrolled. Ultrasonography, CT were examined and compared with histological fibrotic stage. The higher the histological fibrotic stage, the greater the total ultrasonic scores including the parameters of liver surface, edge, parenchyma echogenicity, intrahepatic vessels, and the size of spleen. By receiver operating curve analysis, the sensitivity to distinguish cirrhosis from chronic hepatitis was 86.1% and specificity was 95.5% if the cu-off value of total ultrasonic score was more than 10. The specificity of CT imaging to diagnosis cirrhosis was 100%, but the sensitivity was only 48.5%. The total ultrasonic score had high specificity and sensitivity in diagnosing early cirrhosis. The characteristic CT imaging had high specificity but low sensitivity in diagnosing early cirrhosis.
