Contrast-enhanced ultrasound (CEUS) is increasingly performed for focal liver lesion evaluation because of its high safety profile and ability to yield a definitive diagnosis in many patients, obviating multiphase CT or MRI. CEUS uses specific ultrasound contrast agents (UCAs) that are exceedingly safe, without the risk of renal or liver toxicity. UCAs are cleared rapidly from the body, allowing for multiple injections during a single examination, with no potential for deposition in the patient. This review highlights the performance of CEUS for liver lesion evaluation and illustrates the imaging appearance of common liver lesions in children and adults.
超声造影（CEUS）在评估局灶性肝脏病变方面应用日益广泛，因其具有很高的安全性，在许多患者中能够做出明确诊断，从而避免了多期 CT 或 MRI 检查。CEUS 使用特定的超声造影剂（UCA），其安全性极高，没有肾或肝毒性的风险。UCA 能迅速从体内清除，允许在单次检查中多次注射，患者体内不会有潜在的沉积。本综述强调了 CEUS 在肝脏病变评估中的作用，并说明了儿童和成人常见肝脏病变的影像学表现。
