Non-invasive self-gated IntraGate FLASH sequence
(IG-FALSH) was used to perform cardiac imaging by
reducing motion artifacts. However, IG sequence requires
large repetitions to reduce the motion artifact and
hence was hard to examine high spatial or temporal
resolution cardiac imaging. In this study, we
demonstrate the capability of implementing W=2
acceleration Single Carrier Wideband MRI on IG-FLASH
sequence. Moreover, by trading time reduction for higher
spatial resolution, the fine structures such as valve,
papillary muscles and chordae tendineae could be
observed more clearly with this new technique.
