Estimation of single‐kidney glomerular filtration rate without exogenous contrast agent

Measurement of single‐kidney filtration fraction and glomerular filtration rate (GFR) without exogenous contrast is clinically important to assess renal function and pathophysiology, especially for patients with comprised renal function. The objective of this study is to develop a novel MR‐based tool for noninvasive quantification of renal function using conventional MR arterial spin labeling water as endogenous tracer.
