Diffusion . is the movement of particles from an area of high concentration to an area of low concentration. When a particle moves from an area of high concentration to an area of low concentration, it is said that it is moving down its . Molecules are always moving.

This category of MRI contrast mechanisms is useful for assessing live tissue functions:. Magnetic Field. While MRI is considered to be a safe imaging technique, it is not without hazards. The magnet field will attract many ferromagnetic metals in an uncontrolled fashion and cause them to fly towards the magnets bore and turning them into high velocity projectiles. The bore of the magnet is where the fringe field is strongest, as all the lines of force are constricted and their relative strengths heightened. Various objects can be considered projectiles. Diffusion is a process of . mass transport. that involves the atomic . or molecular motion. .. In the simplest form, the diffusion can be defined as the . random walk. of an ensemble of particles from regions of high concentration to regions of lower concentration.
