Estimating chemical and microstructural heterogeneity by correlating relaxation and diffusion

Whereas diffusion NMR can probe the structural configurations of microscopic environments in biological tissue, relaxation can provide complementary information mainly related to their chemical composition. This chapter considers experiments in which diffusion and relaxation properties are sampled simultaneously by varying multiple acquisition parameters. As such, correlations between the diffusion and relaxation can be established, providing an altogether more complete picture of heterogeneous tissue
