Magnetic resonance elastography (MRE) is an emerging noninvasive technique, an alternative to palpation for quantitative assessment of biomechanical properties of tissue. In MRE, tissue stiffness information is obtained by a 3-step process, propagating mechanical waves in the tissues, measuring the wave propagation using modified magnetic resonance (MR) pulse sequences, and generating the quantitative stiffness maps from the MR images. MRE is clinically used in patients with liver diseases, whereas its applications in other organs are still being investigated. At present, the pediatric studies are in the initial stage and preliminary results promise to provide additional information about tissue characteristics.
磁共振弹性成像（MRE）是一种新兴的无创技术，可替代触诊对组织生物力学特性进行定量评估。在 MRE 中，通过 3 个步骤获取组织的硬度信息，在组织中传播机械波，使用改良的磁共振（MR）脉冲序列测量波传播，以及从 MR 图像生成定量硬度图。MRE 已在肝病患者中临床应用，而其在其他器官的应用仍在研究中。目前，儿科研究尚处于初期阶段，初步结果有望提供有关组织特性的更多信息。
