IVIM imaging acquired with two echo times may provide transverse relaxation time of blood fraction, which can be converted to blood oxygen saturation. We confirmed consistent increases in the renal blood oxygen saturation estimated by this method after an oral water load. IVIM imaging may become a non-invasive method to estimate blood oxygen saturation in kidneys.
