"Choosing a Tractography Algorithm: On the Effects of Measurement Noise"


zum Inhalt:

Diffusion MRI tractography has evolved into a widely used, important 
tool within neurosciences, providing the foundation for in-vivo fiber 
anatomy and hence for mapping of structural connectivity in the human 
brain. This renders it crucially important to understand the influence 
of the various MRI imaging artifacts on the tractography results. In 
this paper, we focus on the thermal noise that is present in all MRI 
measurements and compare its effect on the output of several established 
tractography algorithms. We create a reference dataset by denoising with 
a Non-Local Means filter and evaluate the effect of noise added to the 
reference on the tractography results with a Monte-Carlo simulation. Our 
results indicate that among the algorithms tested, the Tensorlines 
approach is the most robust for tracking white matter fiber bundles and 
the Bayes DTI approach should be preferred for calculating gray matter 
structural connectivity.


Alle Interessierten sind im Namen von Prof. Dr. Scheuermann herzlich 
eingeladen.
