“…Therefore, solids have typically lower MR T 2 relaxation times compared to liquids. Additionally, MR T 2 relaxation time is also sensitive to chemical exchange and internal magnetic field gradients [41], in the presence of interfaces between materials of different magnetic susceptibilities, which is measured by MR T 2 * [39]. In the case of MRI, measured T 2 relaxation times can be sensitive to diffusion, to an extent dependent on the experimental imaging parameters.…”
