Due to the risk for inducing nephrogenic systemic fibrosis (NSF) there is a need for developing angiography without the use of contrast agents, in particular for patients with renal disease. MRA of the renal arteries was obtained using a balanced steady-state-free-precession (B-SSFP) method with a slab selective inversion prepulse in combination with ProSet, SPAIR and SPIR fat saturation and the images were compared with respect to fat suppression and CNR. The ProSet technique (water selective excitation with binomial pulses) were most effective for fat saturation and produced highest vessel/muscle CNR using this sequence.
