Magnetic resonance elastography (MRE) has been introduced for clinical evaluation of liver fibrosis for nearly a decade. MRE has proven to be a robust and accurate technique for diagnosis and staging of liver fibrosis. As clinical experience with MRE grows, the possible role in evaluation of other diffuse and focal disorders of liver is emerging. Stiffness maps provide an opportunity to evaluate mechanical properties within a large volume of liver tissue. This enables appreciation of spatial heterogeneity of stiffness. Stiffness maps may reveal characteristic and differentiating features of chronic liver diseases and focal liver lesions and therefore provide useful information for clinical management. The objective of this pictorial review is to recapture the essentials of MRE technique and illustrate with examples, the utility of stiffness maps in other chronic liver disorders and focal liver lesions.
磁共振弹性成像（MRE）在近十年中已被引入用于临床评估肝纤维化。MRE 已被证明是诊断和分期肝纤维化的一种强大而准确的技术。随着 MRE 的临床应用经验的增长，其在评估其他弥漫性和局灶性肝脏疾病中的可能作用也逐渐显现。硬度图提供了评估肝组织内大范围机械性能的机会。这使得能够了解硬度的空间异质性。硬度图可能揭示慢性肝病和局灶性肝病变的特征性和区分性特征，因此为临床管理提供了有用的信息。本影像学综述的目的是重新掌握 MRE 技术的要点，并通过实例说明硬度图在其他慢性肝脏疾病和局灶性肝病变中的应用。
