The use of ultrasonography (US) to detect and characterize diffuse liver disease can be challenging, but remains a useful tool for the diagnosis and management of many diffuse parenchymal liver diseases such as cirrhosis, steatosis, and malignancies. Newer techniques, such as elastography, are proving useful for earlier detection of hepatic parenchymal changes. The role of US in the assessment of possible biliary ductal obstruction is well established, and Doppler US may provide additional physiologic information regarding hepatic blood flow. US plays a central role in target selection and guidance of percutaneous liver biopsies.
使用超声检查（US）来检测和鉴别弥漫性肝病可能具有挑战性，但它仍然是诊断和管理许多弥漫性肝实质疾病（如肝硬化、脂肪变性和恶性肿瘤）的有用工具。诸如弹性成像等新技术已证明对早期检测肝实质变化有用。US在评估可能的胆管梗阻方面的作用已得到充分确立，并且多普勒超声可能会提供有关肝血流的额外生理信息。US在经皮肝活检的靶点选择和引导中起着核心作用。
