The aim of the present study was to evaluate the feasibility of noncontrast MR angiography of the renal arteries using an Inflow Inversion Recovery (IFIR) sequence in healthy volunteers at 3.0 T. In nine of 10 cases, MR angiography with excellent image quality was obtained and both sides of renal arteries were finely delineated including peripheral branches. In four of 10 cases, two left renal arteries were observed. In addition, in one of four, two right renal arteries were also observed. The renal arteries were finely delineated by means of noncontrast MR angiography using an IFIR sequence at 3.0 T.
