Real-time multi-parametric MR temperature imaging using
a multi-echo gradient-echo (MGE) can simultaneously
provide temperature information from PRF as well as
information on tissue damage. This work is focused on an
extended MGE sequence. By using echo-shifting, higher
spectral resolution data can be accumulated over
multiple time points to provide higher resolution PRF
and R2* measurements and un-aliasing capabilities along
with dynamic PRF, R2* and T1 mapping for interventions.
