How does Whole-Body Diffusion work?

Whole-Body Diffusion is based on a simple physical phenomenon, described by Albert Einstein in 1905: the diffusion of water molecules. DWB detects the diffusion and movement of water molecules between body cells. When they are “trapped” in a hypercellular tissue (whose cells, that is, are very dense, crowded, as is the case with tumours), H2O molecules show restricted diffusion and faster movements. These areas are “bright” in the images obtained with this particular Magnetic Resonance scan. This makes it possible to distinguish the tumour areas from the surrounding healthy tissues and therefore makes it possible to detect lesions measuring a few millimetres.
