Tóm tắt

PURPOSE: The single reference variable flip angle sequence with a multi-echo stack of stars acquisition (SR-VFA-SoS) simultaneously measures temperature change using proton resonance frequency (PRF) shift and T METHODS: Simultaneous PRF shift thermometry and T RESULTS: Using k-space weighted image contrast reconstruction, temporal resolution of 1.71 s was achieved for simultaneous thermometry at 1.5 × 1.5 × 2 mm voxel resolution. PRF shift thermometry was not sensitive to heating in fat. T CONCLUSION: The SR-VFA-SoS sequence was shown to simultaneously measure temperature change using PRF shift and T
