In this study, a 2D-RF ASE EPI sequence with flow dephasing gradient was employed to acquire images that have different susceptibility weighting. Subsequently, based on the theoretical model proposed by Yablonskiy and Haacke  for characterizing signal changes in the presence of deoxyhemoglobin, R2and Oxygen Extraction Fraction (OEF) were estimated from the acquired images. We show that this sequence can dynamically monitor renal function and can be used to study and treat renal disease.
