We will give a new derivation of the Bloch-Torrey equation that governs the behaviour of water molecules in porous media and biological tissues. We will show that this new derivation reveals new term that was ignored in the past. We further show how one can solve this equation analytically for few specific geometries. These solutions enables us to solve the inverse problem of finding the geometric parameters at a micron level from NMR measurements.
These predictions are verified in many experiments paving the way to new MRI modality.
