将体素内非相干运动（IVIM）灌注和弥散成像模型应用于单侧肾动脉狭窄的在体犬模型，并与放射性微球测定相对肾血流量进行比较。用放射性微球测定的相对肾血流量百分比与表观扩散系数百分比密切相关。如果这种方法可以适用于人体成像，它可能会提供一个非侵入性的手段来检测肾动脉狭窄。
The intravoxel incoherent motion (IVIM) model of perfusion and diffusion imaging was applied to an in vivo canine model of unilateral renal artery stenosis and was compared with relative renal blood flow determination with radioactive microspheres. The percentage relative renal blood flow as determined with radioactive microspheres correlated closely with the percentage apparent diffusion coefficient. If this method can be adapted to human imaging, it may provide a noninvasive means for detecting renal artery stenosis.
