We validate the feasibility of currently-used parallel
imaging methods (GRAPPA, SPIRiT and ESPIRiT) for the
reconstruction of temperature maps using model-based PRF
methods. All of GRAPPA, SPIRiT and ESPIRiT result in
temperature errors lower than 2 and ESPIRiT has the
best temperature accuracy with a value of 1.55 at a
reduction factor of 4.
