本研究的目的是前瞻性评价动脉自旋标记技术、血流敏感交替反转恢复（FAIR）快速成像与稳态进动（FISP）对无肾动脉狭窄（RAS）病史和经证实的RAS患者的肾灌注进行无创定量。该研究得到了当地伦理委员会的批准，所有参与者都提供了书面知情同意书。6例高血压但无肾动脉疾病史的患者和12例RAS患者在全身1.5 T单位下进行FAIR真FISP磁共振（MR）成像。RAS分级和动脉造影灌注数据作为参考标准。在FAIR真FISP灌注图像上，重度RAS（> 70%管腔狭窄）可与无或轻度RAS和中度RAS（
me purpose of this study was to prospectively evaluate on arterial spin-labeling technique, flow-sensitive alternating inversion-recovery (FAIR) fast imaging with steady, state precession (FISP), for noninvasive quantification, of renal perfusion in patients without a history of renal artery stenosis (RAS) and in patients with proved RAS. The study was approved by the local ethics committee, and all participants provided written informed consent. Six patients with hypertension but no history of renal artery disease and 12 patients with RAS tinder-went FAIR true FISP magnetic resonance (MR) imaging in a whole-body 1.5-T unit. RAS grade and scintigraphic perfusion data served as reference standards. On the FAIR true FISP perfusion images, severe RAS (> 70% luminal narrowing) could be clearly, distinguished from no or mild RAS and moderate RAS (
