Utilization of balanced steady-state free precession (bSSFP)
at 3.0T is significantly hampered by the elevated B0 and
local RF field inhomogeneities that generally lead to
degraded image quality. In this work, we propose a
refined sequence with binomial pre-saturation and
Kaiser-Bessel startup pulses to provide a more
homogeneous excitation and to suppress the well known
dark band artifacts. This sequence, incorporating VERSE
pulses and parallel imaging, achieves acquisition of a
3D targeted volume covering the major coronaries within
a single breath-hold. Initial studies in healthy
subjects and in a patient with established coronary
artery disease demonstrate image quality improvements in
breath-hold bSSFP at 3.0T.
