Diffusion tensor imaging (DTI) is one of the most
powerful magnetic resonance imaging (MRI) techniques developed in the twentieth
century. In spite of the fact that DTI has been in use for more than twodecades, it is still hard to find publications that simplify mathematics behind
DTI for DTI users without extensive mathematical background. We believe that
this may prevent some researchers from using DTI technique to its fullest
extent.
To the best of our knowledge, there are no published reviews which have
tried to clarify the methods of DTI measurement and analysis. In this article,
we attempted to explain the mathematics of DTI in simple terms with the goal of
providing DTI users, with a better understanding of this technique and its
usage. In addition, we have also described the DTI processing steps and
explained the reasons behind each step.(Read more)
