Glomerular filtration rate (GFR) measurements have been
studied with various kinetic models, however, all these
techniques are based on gadolinium contrast agent.
Arterial blood spin labeling MR imaging uses the water
spins of blood as an endogenous tracer, therefore it is
completely noninvasive. In this study, we aimed to
investigate the variable-TE based FAIR-ASL technique in
measuring GFR in human kidneys. Volunteer experiments
show good reproducibility of the established method in
renal function estimation.
