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.
