Overview of diffusion imaging.
Diffusion is a major advance in the continuing evolution of MR imaging. It provides contrasts and characterization between tissues at a cellular level that may imply differences in function as well as framework. With the development of echo-planar imaging (EPImh54) diffusion the quality of the data will be such that clinically relevant information can result, and thus clinical usage of EPI diffusion will increase. Many potential applications of diffusion have not yet been explored.
