We
demonstrate the feasibility of obtaining free-breathing cine images utilizing
a single respiratory navigator gating technique. This method was made
possible by utilizing the high signal-to-noise ratio (SNR) available at 3T to
apply parallel imaging methods allowing the acquisition of up to 30 cardiac
phases within clinically acceptable imaging time. Compared to traditional
breath-holding techniques this methods showed no statistical difference in
qualitative and quantitative imaging parameters, thereby, could be used as an
alternative for children and patients who are unable to hold their breath.
