Repetitive MR thermometry was performed on the brain of nine volunteers using GRE, seg EPI, and ss EPI sequences on whole-body 1.5 T and 3 T clinical systems using comparable acquisition parameters. Phase stability and temperature data precision in the human head were determined over 12 minutes for the three sequences at both field strengths. The ss EPI sequence was the fastest and the most precise sequence for MR thermometry, with significantly higher accuracy compared to GRE. An ex-vivo swine skeletal muscle model was used to evaluate temperature accuracy of the ss EPI sequence during heating by high intensity focused ultrasound (HIFU).
