目的 研究B超二维图像及彩色多普勒血流影像 (CDFI)对监测肝纤维化的价值。方法 181例病理证实的慢性肝炎病人按病理纤维化分级分为 5组 ,比较其二维超声和CDFI检查结果。结果 肝包膜厚度、肝右叶最大斜径、门静脉主干和左、右支内径、胆道壁厚度、脾长厚径、肝实质光点形态、脾静脉直径和门静脉每分钟血流量参数等指标反映肝纤维化均有较好的敏感性、特异性和准确性。结论 超声二维图象和CDFI在监测肝纤维化方面有一定应用价值 ,其敏感性、准确性和特异性有待通过引进新技术加以提高。
Objective To study the value of B-ultrasound and color Doppler flow imaging (CDFI) in monitoring liver fibrosis. Methods A total of 181 patients with pathologically confirmed chronic hepatitis were divided into five groups according to their pathological fibrosis grades. The results of two-dimensional ultrasonography and CDFI were compared. Results The indexes of hepatic capsule thickness, maximal diameter of right hepatic lobe, diameter of portal vein, diameter of left and right branch, thickness of biliary tract, thickness of spleen, shape of hepatic parenchyma, diameter of splenic vein and per minute blood flow of portal vein Liver fibrosis has better sensitivity, specificity and accuracy. Conclusion Ultrasound two-dimensional images and CDFI have certain value in monitoring liver fibrosis. The sensitivity, accuracy and specificity need to be improved by introducing new technologies.
