The aim was to assess the T1 and T2 temperature dependence of human adipose breast tissue and compare these with sunflower oil and pig fat. The temperature of tissue samples were increased by heating a water bath from 26.5C to 72C and then allowed to cool. During heating and cooling, the temperature was measured with a fiber optic probe and T1 and T2 were mapped. Reversible T1 changes but irreversible T2 changes were found for breast and pig fat. The T1-temperature dependence was similar for all three samples. T2 had a larger temperature dependence for pig than for breast fat.
