Dynamically phase-cycled radial bSSFP (DYPR-SSFP) is a
recently proposed method for fast, banding-free bSSFP
imaging. Based on a dynamically changing phase-increment
in combination with a (quasi-) randomly sampled radial
trajectory, images without banding artifacts can be
obtained from one single acquisition. Up to now, the
DYPR-SSFP concept has been combined with a 2D radial
trajectory, yielding slight artifacts due to the applied
dynamic phase-increment. Here, the combination with a 3D
radial trajectory is proposed, effectively mitigating
this drawback and allowing the generation of 3D
banding-free bSSFP images with high isotropic
resolution.
