This study demonstrates a method for simultaneous monitoring of temperature rise during spin echo based MR - ARFI acquisitions. An additional readout gradient was inserted after the excitation pulse in order to enable gradient echo acquisition. Temperature rise was measured using the gradient echo phase difference images for a range of FUS acoustic power levels.
