Extension Description

DiffusionComplexityMap-logo.png

Diffusion-weighted images (DWI) and Diffusion Tensor Imaging (DTI) are well-known and powerful imaging techniques in MRI. For DTI images, the most used measurements are the fractional anisotropy (FA) and apparent diffusion coefficient (ADC). However, the limitations of FA and ADC formalism are also vastly debated due to low tissue contrast for ADC maps and measurement artifacts present in crossing-fiber orientation for FA maps. Although the DTI evaluation has evolved continually in recent years, there are still struggles regarding the quantitative measurement that can benefit brain areas that are consistently difficult to measure on diffusion-based methods, e.g., the grey matter (GM). The present Slicer extension proposes offer an image processing technique using the principle of diffusion distribution evaluation regarding the LMC complexity measure, named Diffusion Complexity (DC). [1].


Modules


Use Cases

  • Use Case 1: Obtain a complementary scalar information using clinical DTI image acquisition protocol (DC Map)
    • The DC map is a new scalar mapping that can give an additional information to analyse diffusion image sequences, without changing the MRI imaging protocol.
  • Use Case 2: Gain focus on Gray Matter analysis using diffusion images
    • DC map has a signal peak in GM tissue, which can be important to discriminate brain diseases in this particular brain tissue that is challenging to other classical DTI maps (e.g. FA and ADC)
  • Use Case 3: Interpret the diffusion data in light of statistical physics information theory
    • The DC map is based on the López-Ruiz, Mancini, and Calbet (LMC) information theory definition, giving the contribution of classical entropy (Shannon's entropy) and the disequilibrium function. Hence, another way to interpret the diffusion data can be given by this new technique.
