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.
