On state-of-the-art magnetic resonance imaging, most lesions can be detected and characterized with confidence according to well-known criteria. However, atypical characteristics in some common lesions and the incidental encounter with rare lesions may pose diagnostic difficulties. In this article, six challenging hepatic lesions will be discussed and evaluated on the most important magnetic resonance imaging sequences, with histological correlation when available. In addition, the background information concerning these lesions will be described based on the most recent available literature. By reading this article, the reader will be able to (1) categorize the lesion in solid and fluid-containing lesions, based on the T2 signal intensity; and (2) define the benign or malignant nature of the lesion, in relation to the signal intensity and dynamic enhancement pattern, despite the presence of atypical characteristics of some lesions.
在先进的磁共振成像技术下，根据众所周知的标准，大多数病变能够被可靠地检测和定性。然而，一些常见病变的非典型特征以及偶然发现的罕见病变可能会带来诊断困难。在本文中，将对六个具有挑战性的肝脏病变进行讨论，并在最重要的磁共振成像序列上进行评估，如有可用的组织学相关性则一并考量。此外，将根据最新的现有文献描述这些病变的背景信息。通过阅读本文，读者将能够：（1）根据T2信号强度将病变分类为实性和含液性病变；（2）尽管某些病变存在非典型特征，但根据信号强度和动态增强模式确定病变的良性或恶性性质。
