This study developed an approach for renal perfusion and glomerular filtration rate mapping based on the combination of pulsed arterial spin labeling technique and a spin-echo EPI with multiple TEs sequence on clinical 3T MR. Each of ten healthy young subjects accepted 12 breath-hold ASL scans for different TEs acquisition. Based on the proposed method, the RBF, blood R2* and GFR maps were obtained simultaneously. We hope that this MR technique can be combined with other functional methods to provide a complete noninvasive assessment of renal status in a single examination.
