DTI Tractography Challenge MICCAI 2012

Introduction

The 2nd Edition of the MICCAI Grand Challenge on DTI Tractography will be held on Monday October 1st, 2012, as part of the 15th International conference on Medical Image Computing and Computer Assisted Intervention (MICCAI 2012) in Nice, France. The first Edition of the challenge was held at MICCAI 2011 in Toronto.

Outline

DTI tractography holds promises for mapping white matter pathways in-vivo. However, the validation of tractography results remains the major bottleneck to clinical usability and utility, since neurosurgeons and scientists face the challenge of selecting the appropriate tractography method in the absence of ground truth. This workshop aims at comparing tractography algorithms performances in the reconstruction of the corticospinal tract in a controlled environment using software generated DTI phantoms and in a clinical workflow of neurosurgical cases. Quantitative evaluation criteria will be based on fiber diffusion profiles, fiber geometry and distance between bundles. Clinical assessment will focus on anatomical correctness, depiction of lesion infiltration and tract displacement.
