An MR thermometry (MRT) method with field monitoring is proposed to improve the measurement of small temperature variations. MRT experiments were performed at 7T with concurrent radiofrequency heating and field monitoring on an agar-gel phantom and in vivo. Inclusion of field fluctuations in image reconstruction showed beneficial for the measurement of small temperature rises as encountered in standard brain exams.
