There has been no systemic evaluation for transplanted kidney patients using 3T MRI system with pseudo-continuous ASL (pCASL). In this study, we presented multi-parametric renal perfusion imaging on transplanted kidney patients using multi-delay pCASL with bSSFP readout. Influence of background suppression on temporal signal stability was investigated and two different perfusion quantification models were compared. Multi-parametric perfusion signals including mean renal perfusion and arterial transit time were measured for transplanted kidney patients. The current study would be helpful for applying multi-delay pCASL to routine clinical diagnosis of transplanted kidney patients.
