摘要
目的探讨彩色多普勒超声在慢性肝炎肝纤维化分期诊断中的应用价值。方法对192例慢性肝炎肝纤维化患者进行超声及肝活检组织学检查,并选择50例健康人作为对照,将肝超声定量指标与肝组织病理纤维化分期进行对比分析。结果在超声定量指标中脾脏长径、脾静脉内径、门静脉主干内径、门静脉最大流速与肝纤维化分期关系密切,在各组间差异有统计学意义（P〈0.05或P〈0.01）;当分别取诊断界限值：12.0cm、6.9mm、12.2mm和21.5cm/s时,敏感度和特异度均可达到60%~80%。结论彩色多普勒超声一种是无创的、能客观评价肝纤维化程度的检查方法。
Objective To explore the clinical value of color Doppler ultrasound in the staging of liver fibrosis in chronic hepatitis. Methods 192 patients with liver fibrosis were examined on ultrasound and liver biopsy, and 50 cases of healthy people as a comparison. The liver ultrasound quantitative indicators and liver tissue pathological fibrosis stage was compared and analyzed. Results Spleen diameter, the inner diameter of the splenic vein, and portal vein diameter, portal vein maximum flow rate is closely related with the stage of liver fibrosis, differences between groups were statistically significant （P〈0.05 or P〈0.01）. When the diagnostic threshold values were： 12.0cm, 6.9mm, 12.2mm and 21.5crrds, the sensitivity and specificity can reach 60% to 80%. Conclusion The color Doppler ultrasound is a noninvasive, objective evaluation method of liver fibrosis degree.
