In the paper by Pohlmann et al., the feasi- bility of intravascular contrast-enhanced MRI is examined for monitoring renal blood volume fraction. Findings provide a foundation towards advancing multi- parametric MRI for renal blood volume mapping to ultimately yield an image- based renal MR oximetry measure for assessment of acute kidney injury.
