This study evaluates reliability of current technology for measurement of renal arterial blood flow by breath‐held velocity‐encoded MRI. Overall accuracy was determined by comparing MRI measurements with known flow in controlled‐flow‐loop phantom studies. Measurements using prospective and retrospec...
