Cartesian
and radial balanced SSFP (bSSFP) sequences are widely used clinically for
dynamic cardiac imaging. Dynamic spiral sequences have been used in many
research studies, but clinical adoption has been slow. One goal of this study is to compare radial
and spiral dynamic balanced SSFP scanning. The other goal is to develop a new
spiral-in/spiral-out bSSFP pulse sequence to achieve flow compensation
through symmetry and to exploit the bSSFP refocusing mechanism at TE =
TR/2. We compared this new sequence to
radial bSSFP and spiral-out bSSFP with flow-compensated rewinders.
