Kidney operates an important organ remaining the homeostasis, the water-electrolyte balance, and discharging the metabolites in vivo, while the oxygenantion plays a key role in renal function and disorders. Blood oxygen level-dependent magnetic resonance imaging (BOLD MRI) is a non-invasive functional technology to evaluate the renal oxygen, which can not only display the morphological structure imaging, but also investigate the metabolism, the function, and the molecular level of the kidneys, up to now, it has been made great progresses in the diagnosis, the differentiation, and the therapeutic response of nephropathy. This article will review the clinical progresses with BOLD MRI of the kidneys in the past few years.%肾脏是机体保持内环境稳定、调节水和电解质平衡状态、排出体内代谢物的关键器官,肾实质氧合状态在其生理功能发挥、疾病发生发展中具有重要意义.血氧水平依赖性成像作为无创性评价肾内氧代谢功能技术,可实现生理研究从解剖展示向代谢、功能和分子水平迈进,对肾病诊断、鉴别与疗效评估发挥日益明显的作用,本文就近年血氧水平依赖磁共振成像对肾脏研究展开综述.
