There is a large interest in understanding the biophysical properties of BAT, WAT, and beige adipose tissues for evaluating its potential to improve whole body metabolism. Diffusion properties of tissues provide information on microstructure, anisotropy, and pathology. In the presence of cellular and sub-cellular barriers, and heterogeneity the lipid diffusion is restricted. Water diffusion has been well characterized in several organs. Fat diffusion has not been studied due to the hardware limitations. In this study, we have implemented diffusion-weighted spectroscopy for investigating in-vivo diffusion properties of BAT and WAT.
