Since the advent of second generation ultrasound (US) contrast agents, ultrasound has caught up with other imaging modalities for the detection and characterization of liver metastases and as a result of its high temporal and spatial resolution it can in some cases even be superior to computed tomography (CT) and magnetic resonance imaging (MRI). Many studies have demonstrated a sensitivity and specificity of over 90%. Due to its high temporal resolution contrast-enhanced US (CEUS) is capable of detecting even a very short duration of hyper-enhancement during the arterial phase. Radiation protection and lack of adverse effects on renal or thyroid function are additional arguments why CEUS should be recommended as the first imaging modality in the evaluation of hepatic metastases in cases of favorable scanning conditions.
自第二代超声（US）造影剂问世以来，超声在肝转移瘤的检测和特征描述方面已赶上其他成像方式，并且由于其高时间和空间分辨率，在某些情况下甚至优于计算机断层扫描（CT）和磁共振成像（MRI）。许多研究已证明其敏感性和特异性超过90%。由于具有高时间分辨率，超声造影增强（CEUS）甚至能够检测到动脉期极短时间的高增强。辐射防护以及对肾脏或甲状腺功能无不良影响是在扫描条件良好的情况下推荐CEUS作为肝转移瘤评估的首选成像方式的额外理由。
