In this study, short-term effects of furosemide on renal perfusion were investigated by using FAIR-ASL at 3T MR. Baseline and post ASL images were acquired on healthy subjects before and after furosemide administration to measure the renal hemodynamic response. Furosemide produced a remarkable reduction in medullar RBF, while cortical and global RBF changes did not reach a significant level. Furosemide administration is associated with a prominent decrease in the medullar blood perfusion, but its hemodynamic effects on the renal cortex still need further study, while ASL-MRI provides an alternative way to noninvasively monitor changes in renal function.
