Figure Lengend Snippet: a) Sequence diagram of gradient-modulated SWIFT, b) retrospective gating strategy using DC navigator acquisitions and c) an example DC navigator signal fluctuation due to respiratory motion. DC navigator acquisitions were inserted every 16 TRs (~40 ms interval). Respiratory motion was extracted based on the signal drop in the DC navigator signals at the inhalation phase (gray dots in c).
Article Snippet: In SWIFT, DC navigator signal acquisitions were inserted every 16 TRs, where the gradients were turned off ( ); therefore, all DC navigator acquisitions were identical and the signal fluctuations were predominantly due to respiratory motion.
