Description
Summary:Purpose To evaluate renal allograft vessels in the early period after kidney transplantation with three‐dimensional (3D) contrast‐enhanced MR angiography (3D CE MRA) using a parallel imaging technique. Materials and Methods Sixty‐three consecutive patients were examined with 3D CE MRA and integrated SENSE technique (Sensitivity Encoding) 2 to 21 days after renal transplantation. MR angiography studies were analyzed for the presence of arterial stenosis. The degree of renal transplant artery stenosis was graded qualitatively as 0.19) but significantly different from those with severe stenoses (P < 0.05). Conclusion The incidence of mild and moderate vessel narrowing at the arterial anastomosis is unexpectedly high in the early period after kidney transplantation and is most likely due to surgery‐related tissue edema.
