Continuous Fat Suppression During Respiratory Triggering

Alto Stemmer¹, Berthold Kiefer¹

Slices acquired at the beginning of the acquisition period of a respiratory triggered sequence may suffer from insufficient fat suppression, if a spectral selective saturation or inversion pulse is used for fat suppression. The proposed reason is the interruption of fat steady state during inspiration while the sequence waits on the next trigger. In this work the sequence of fat suppression modules is continued in the trigger pauses. This maintains the steady state and results in consistent fat suppression in all slices.
