The goal of the present study was to perform IVIM-DWI and non-contrast MRA of graft kidneys to evaluate the micro- and micro-structural status in 17 patients within 48 hours after transplantation. Five of them had a second scan in six months later. The experimental results suggested that D*, D and f values in IVIM-DWI might considerably be useful in early detection of functional change graft kidneys and non-contrast MRA and PC-MRI could effectively assess patency and flow rates of graft vessels. Combination of both IVIM-DWI and non-contrast MRA would be potentially promising in clinical application for monitoring graft kidneys.
