Background: Post-surgical evaluations of the renal arteries is essential in living donor renal transplantation. CT angiography (CTA) is not a method of choice since it requires nephrotoxic iodinated contrast media. Enhanced MR angiography (MRA) could not replace CTA in the wake of NSF issues. Purpose: to assess the feasibility of non-contrast MRA using 3D PC-VIPR in depicting the renal artery after renal transplantation. Method: Consecutive seven living donors ( male, female, median age of ) underwent CTA on 64 detector row scanner before the transplantation, and seven recepients underwent MRA including 3D PC-VIPR , using a 3 Tesla system after the transplantation. 5-segments (i.e.,main stem and 1st to 4th order of brances) were assessed by two independent readers.Result: the evaluations by 2 observers for segment 1 to 5 were as follows : observer 1: 100%, 100%, 89%, 75%, 66%; observer 2: 100%, 100%, 90%, 80%, 71%.κstatistic (κ= 0.731(z=7.73373, P<0.0001)) Conclusion: Non-enhanced renal artery depiction is feasible with 3D PC-VIPR with comparable delineations to CTA up to secondary brances with excellent inter-observer agreements.
