THE MANY DIFFERENT local environments of hydrogen nuclei within tissue give rise to complicated magnetic relaxation behavior while ensuring the rich and diverse contrast seen in magnetic resonance (MR) imaging. From an operational point of view, it has proved convenient to classify the multiple envi

In this study the exchange between 'H magnetization in "free" water ( 'Hf) and that in a pool with restricted motion (' H,) was observed in tissues in vivo using NMR saturation transfer methods. Exchange between these two pools was demonstrated by a decrease in the steady-state magnetization and rel
## Abstract Cross relaxation between macromolecular protons and water protons is known to be important in biologic tissue. In magnetic resonance (MR) imaging sequences, selective saturation of the characteristically short T2 macromolecular proton pool can produce contrast called magnetization trans
