MRI of the kidney currently makes the transition from depiction of morphology to assessment of function. Functional renal imaging methods provide information on diffusion and perfusion on a microstructural level. This review article presents the current status of functional renal imaging with focus on DWI (diffusion-weighted imaging) and DCE-MRI (dynamic contrast-enhanced MRI), as well as BOLD (blood-oxygenation level dependent) MRI, DTI (diffusion tensor imaging) and arterial spin labeling (ASL). Technical background of these techniques is explained and clinical assessment of renal function, parenchymal disease, transplant function and solid masses is discussed.
MRI 肾脏目前正在从形态学描述过渡到功能评估。功能肾成像方法提供微观结构水平上的扩散和灌注信息。本文综述了功能肾成像的现状，重点介绍了 DWI（扩散加权成像）和 DCE-MRI（动态对比增强 MRI），以及 BOLD（血氧水平依赖）MRI、DTI（扩散张量成像）和动脉自旋标记（ASL）。解释了这些技术的技术背景，并讨论了肾功能、实质疾病、移植功能和实体肿块的临床评估。
