A new workflow was developed for the extraction of a
radial self-gating signal in mice from an Inversion
Recovery Snapshot FLASH sequence. The new method almost
completely removes the T1 relaxation background and the
phase shift caused by the inversion of blood
magnetization at the zero-crossing point. A comparison
of the self-gating signal with an additional monitored
ECG signal showed small deviations for the trigger
points extracted from the radial data even at the
beginning of the inversion. Both the k-space signal and
the reference were used for retrospective global and
slice-selective T1 mapping and yield matching T1 values.
