Previous results for the measurement of T 1 as a means of monitoring temperature have demonstrated a linear calibration with a coefficient of the order of 1.5%C. We have studied the changes in T 1 , further, and observe that changes in tissue perfusion are substantial contributors to the effects observed, and that the model of what is happening is complex and may not permit a simple temperature calibration.
