Reproducibility and reliability of the DTI fiber tracking algorithm integrated in the Sisyphe software

Abstract

Diffusion Tensor Imaging (DTI) and tractography are able to model fiber architecture within the white matter. In the laboratory, we developped a software Sisyphe, which is an integrated environment for neuroimaging post-processing and visualization. In this work, we extend this tool to further incorporate white matter DTI fiber tracking. We evaluate the reproducibility and reliability of our algorithm by studying the pyramidal tract.
