Abstract

The purpose of this work is to demonstrate how temperature can be derived from MRE data. A 1.5% agarose phantom was heated slowly during this temperature trial. The temperature was measured using a fluorescent thermometer while MRE data were acquired. The phase average from the MRE acquisition was used to calculate the phase shift induced by the proton resonance frequency shift (PRF shift) associated with the temperature change. Our data correlate well with the temperature change recorded by thermometer.
