The liver is more often involved with metastatic disease than primary liver tumors. The accurate detection and characterization of liver metastases are crucial since patient management depends on it. The imaging options, mainly consisting of contrast-enhanced ultrasound (CEUS), multidetector computed tomography (CT), magnetic resonance imaging (MRI) with diffusion-weighted imaging (DWI), extra-cellular contrast media and liver-specific contrast media as well as positron emission tomography/computed tomography (PET/CT), are constantly evolving. PET/MRI is a more recent hybrid method and a topic of major interest concerning liver metastases detection and characterization. This review gives a brief overview about the spectrum of imaging findings and focus on an update about the performance, advantages and potential limitations of each modality as well as current developments and innovations.
肝脏比原发性肝肿瘤更常发生转移。准确检测和描述肝转移对于患者的管理至关重要。成像选择主要包括增强超声（CEUS）、多排计算机断层扫描（CT）、磁共振成像（MRI）联合弥散加权成像（DWI）、细胞外对比剂和肝脏特异性对比剂以及正电子发射断层扫描/计算机断层扫描（PET/CT），这些方法在不断发展。PET/MRI 是一种较新的混合方法，是关于肝转移检测和特征描述的一个主要研究课题。本文简要概述了成像表现，并重点介绍了每种方法的性能、优势和潜在局限性的最新进展，以及当前的发展和创新。
