Abstract

Focal liver lesions (FLLs) are commonly encountered on routine imaging studies. Most lesions detected are benign, but many are indeterminate at the time of initial imaging. This article reviews the important role of MR imaging for the detection and characterization of various benign FLLs while illustrating typical imaging appearances and potential pitfalls in interpretation. The utility of diffusion-weighted imaging and hepatocyte-specific contrast agents is also discussed.

摘要

局灶性肝病变（FLLs）在常规影像学检查中很常见。检测到的大多数病变是良性的，但许多在初次成像时是不确定的。本文回顾了磁共振成像（MR成像）在各种良性FLLs检测和特征描述中的重要作用，同时阐述了典型的影像表现及解读中可能出现的陷阱。还讨论了扩散加权成像和肝细胞特异性对比剂的应用。
