DTI Tractography for Neurosurgical Planning: A Grand Challenge

Outline: Diffusion Tensor Imaging (DTI) tractography has a unique potential for neurosurgical planning since it provides a window on the organization of white matter pathways in-vivo. During the past decade, the MICCAI community has been a major contributor to the development and refinement of a wide variety of advanced tractography techniques. This workshop will give participants the opportunity to evaluate the performances of their tractography algorithms in a neurosurgical context. Participants will gain insights on the currently available gold-standard for evaluating tractography results in the Operating Room, in the absence of ground truth.

Logistics

The DTI Tractography Challenge workshop will be held on Sunday September 18, 2011 at the Westin Harbour Castle, 1 Harbour Square, Toronto, Canada. To register for the workshop, please visit the MICCAI 2011 conference website. For questions related to this event, please send an e-mail to Sonia Pujol (spujol at bwh.harvard.edu).

Submission

Participants will be required to submit their tractography results and a short paper describing their analysis. The paper should include the following elements 1) a presentation of the DTI analysis pipeline, 2) a description of the tractography technique and parameters used, 3) a set of images providing an intuitive way to present the reconstructed tracts to neurosurgeons. Supplementary materials such as short videos, are encouraged, but not mandatory.

Rules

• Tractography of the tract of interest should be performed in both hemispheres
• Tractography results should include the enveloppe of the reconstructed tracts

Dead-line for submission: June 1st, 2011. Submission procedeure: TBA

Datasets

The workshop datasets will consist four neurosurgical cases acquired at Brigham and Women's Hospital and two healthy subjects. Each dataset will include Anatomical Images (T1,T2 and FLAIR), a Diffusion Weighted Imaging (DWI) volume and a Diffusion Tensor Imaging (DTI) volume. Data will be in the ITK-readable Nrrd file format, which consists of an ASCII readable header file and a separate uncompressed raw image datafile.
