肝病超声诊断指南

Guideline for ultrasonic diagnosis of liver diseases

超声检查无创、实时、价廉,无辐射、便于反复进行,是最常用的肝脏影像学检查方法。近年来,超声检查新技术如超声造影、弹性成像发展迅速,可有效鉴别肝内占位性病变性质、评估肝纤维化和门静脉高压程度以及监测肝病治疗效果,在临床肝病及其介入治疗中发挥重要诊断价值。本指南规范了肝病多模态超声技术(灰阶超声、彩色多普勒超声、超声造影、弹性超声)检查的仪器调置、患者准备及医生检查方法;对肝脏弥漫性病变(炎性病变、纤维化、硬化)、多种占位性病变及肝病介入操作的多模态超声技术诊断标准进行了定义和规范,同时推荐了超声监测周期及肝脏疾病超声诊断报告书写规范。

Ultrasound is a non-invasive,real-time,inexpensive,radiation-free and easily repeatable method,usually used for liver imaging.In recent years,new ultrasound examination techniques for liver diseases such as contrast-enhanced ultrasound and elastography have been rapidly developed,which can effectively identify intrahepatic space-occupying lesions,assess the degree of liver fibrosis and portal hypertension,and monitor the effects of treatment.Therefore,these technologies play an important diagnostic role in clinical liver diseases and have therapeutic interventional value.This guideline classifies the instrument set-up,patient preparation,and physician examination methods through multimodal ultrasound examinations(gray-scale ultrasound,color Doppler ultrasound,contrast-enhanced ultrasound,elastic ultrasound)for liver diseases.In addition,liver diseases multimodal ultrasound technology diagnostic criteria for diffuse hepatic lesions(inflammatory lesions,fibrosis,and sclerosis),multiple space-occupying lesions,and interventional procedures have been defined and standardized.Concurrently,we also recommend the ultrasound monitoring time interval and diagnostic report writing standard for liver diseases.
