ASL imaging is a preeminent noninvasive method to quantify renal blood flow, which may be helpful to understand the pathogenesis of CIN. Our time course study indicates that the iodinated contrast medium can reduce the blood flow in the different zones of kidney. And some differences do exist on the renal blood flow after the two kinds of iodinated CM administration.
