Diffusion tensor imaging (DTI) is being used more and more widely in the diagnosis of central nervous system. Based
on DTI, track density imaging (TDI) is an emerging technique applied to clinical use. This article introduced the
principle and clinical application, analyzed pros and cons, and made conclusion and prospect of these two techniques.
