MEGSE imaging is a preeminent noninvasive method to quantify renal oxygen extraction fraction, which may be helpful to understand the pathogenesis of CIN. Our time course study indicates that the iodinated contrast medium can inrease the OEF in different zones of kidney. And some differences do exist on the renal Oxygen Extraction Fraction (OEF) after the two kinds of iodinated CM administration.
