title: [MR temperature monitoring by the proton phase shift (PPS) method with a 0.3T open-type MR scanner: experimental study].
abstract: Several MR parameters are sensitive to temperature change, notably, T1 relaxation time, proton phase shift (PPS) and diffusion coefficient. The PPS method has been considered for temperature monitoring during laser ablation owing to its tissue-independence and its ability to be used with a mid-magnetic field. Using the PPS method, we experimentally evaluated MR temperature monitoring with a 0.3T open-type MR scanner. Temperature change was reproducibly described as color mapping image. The PPS method was suitable for MR temperature monitoring in interventional MRI.
