The paper describes a modified, PFGSE MR method of measuring diffusion coefficients in heterogeneous materials. The principle of the proposed method consists in measuring the decrease in spin echo when applying diffusion gradients of different polarities. The detected images must be processed using special methods. The method greatly reduces the effect of static magnetic field gradient on the precision of measuring diffusion coefficients.
