A
novel SSFP sequence with interleaved acquisition for F0, F- and F+ was proposed
and applied to T1/T2 relaxometry. The good agreement with analytical solution
of SSFP implies that steady state is maintained at different TR. Compared to
TESS, TEs of the three echoes can be identical to eliminate T2* effect. The reduced
TR decreases susceptibility induced signal void and motion sensitivity. The
crusher in slice select direction avoids the unwanted diffusion effect for high
resolution imaging. The phantom study shows that the T1/T2 relaxometry results
are consistent with the traditional IR-TSE and SE results.
