Temporal constraints in renal perfusion imaging with a 2-compartment model.

Objective: To assess the required temporal resolution and total acquisition time for renal perfusion and filtration measurements with a 2-compartment model.

Material And Methods: Saturation-recovery TurboFLASH perfusion measurements of 15 healthy volunteers were acquired at 1.5 T, with a temporal resolution of 1 second during the first pass and a total acquisition time of 270 seconds.
