Functional MRI is a new and exciting tool enabling non-invasive assessment of renal function. Diffusion-weighted imaging (DWI), diffusion tensor imaging (DTI), blood oxygen level-dependent (BOLD) MRI, and magnetic resonance elastography (MRE) are some of the techniques under investigation. In this article we review the basic principles of these techniques, their possible applications, and their limitations.
功能磁共振成像（Functional MRI）是一种全新且令人兴奋的工具，能够对肾功能进行非侵入性评估。弥散加权成像（DWI）、弥散张量成像（DTI）、血氧水平依赖性功能磁共振成像（BOLD MRI）以及磁共振弹性成像（MRE）是目前正在研究的部分技术。在本文中，我们将综述这些技术的基本原理、可能的应用以及它们的局限性。
