ABSTRACT:
A method of determining and imaging the temperature or temperature change of a liquid or solid object by NMR placing the object in a magnetic field B.sub.o at a temperature T.sub.o.sup.i, subjecting the object or a limited volume thereof to a first series of NMR imaging sequences to obtain first numerical values or images of molecular diffusion coefficients D.sub.o for individual points of the object or the limited volume thereof and recording the first series of images, maintaining the object or limited volume thereof at a temperature T.sup.i or waiting for a spontaneous change to the temperature, subjecting the object to a second series of magnetic resonance imaging sequences to obtain second numerical values or images of molecular diffusion coefficients D.sup.i for the same points of the object or the limited volume thereof and recording the second series of images, comparing point-by point the values or images of the diffusion coefficients D.sub.o.sup.i with the values or images of the diffusion coefficients D.sup.i to generate a third series of values or images representing temperature changes dT.sub.i and recording the third series of images for each point of the object or limited volume thereof from the formula
