超声检查已成为肝纤维化的重要诊断和评价手段。二维超声用于显示肝脏形态及回声,是超声诊断的基础手段,高频超声与组织定征或许能早期发现肝脏回声改变;彩色多普勒和频谱多普勒可以显示肝静脉系统血流情况,可以作为评价肝实质病变程度的指标,超声造影提供了良好的血池示踪剂,能够反映肝脏的血流灌注,从而能够评估肝脏疾病的严重程度;瞬时弹性成像系统为无创性诊断肝纤维化提供了新的发展方向。本文将从超声在反映肝组织结构回声与血流动力学两方面的研究进展进行综述评价。
Ultrasonography has become an important diagnostic and evaluation tool for liver fibrosis. Two-dimensional ultrasound is used to display the liver morphology and echo, which is the basic method of ultrasound diagnosis. High-frequency ultrasound and tissue identification may be able to detect liver echo changes early. Color Doppler and spectral Doppler can show the hepatic venous system blood flow , Which can be used as an index to evaluate the degree of hepatic parenchymal lesion, and CEUS provides a good blood pool tracer to reflect the hepatic perfusion, so as to assess the severity of liver disease. The transient elastography system is a noninvasive diagnostic method for liver fibrosis Provides a new direction of development. This article will review the progress of ultrasound in reflecting the structure of the liver echo and hemodynamics.
