Acute rejection is one of the key influencing factors associated with the survival period of renal allograft. The aim of this study is to find useful indications for diagnosing acute renal allograft rejection in the early stage. The results shows that DKI and ASL were both able to detect the early functional changes by measuring diffusion and perfusion properties of transplanted kidneys, showing a reduction of cortical and medullary values, especially in the cortex.
