Three-dimensional (3D) non-contrast enhanced MR
angiography (NCE-MRA) using flow-sensitive dephasing
(FSD) prepared steady-state free precession (SSFP) had
proved a promising strategy for evaluation of peripheral
vasculature without the use of gadolinium-based contrast
agent. The magnetization preparation with FSD gradients
was used for the blood signal suppression with
advantages of flow-independence. It could be flexibly
configured in both direction and strength so that
multidirectional flow suppression was feasible. The
purpose of this study was to compare the image quality
of pedal arteries acquired from the NCE-MRA technique
with single directional and two-directional FSD modules
preparation, respectively.
