DTI Tractography for Neurosurgical Planning: A Grand Challenge
The DTI Tractography for Neurosurgical Planning Challenge workshop is part of MICCAI 2011, the 14th International Conference on Medical Image Computing and Computer Assisted Intervention to be held from 18th to 22th September 2011 in Toronto, Canada.
Overview: Diffusion Tensor Imaging (DTI) tractography has a unique potential for neurosurgical planning since it provides a window on the complex 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 DTI Tractography for Neurosurgical Planning Challenge 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.

Workshop Format
The workshop will be composed of two parts: the first part will consist of a series of presentations of the tractography algorithms and results by the workshop participants, in parallel with the grand challenge contest; the second part will focus on the results of the contest, and discussions on tractography challenges and clinical use of DTI for neurosurgical planning.
Submission
- Participants will be required to submit a zip archive file containing their tractography results and a short paper.
- The tractography results should include 1) the 3D coordinate of the tracts in the VTK-ASCII file format (vtkPolyData), 2) the enveloppe of the tracts in the ITK-readable Nrrd file format, and 3) three anatomical views (axial, coronal, sagittal) of the tract in png file format.
- The paper should include the following elements 1) a presentation of the DTI analysis pipeline, 2) a description of the tractography techniques and parameters used, 3) a set of images providing an intuitive way to present the reconstructed tracts to neurosurgeons. Participants will be invited to propose an evaluation criteria for their tractography method in the Appendix of the paper.
- Supplementary materials such as short videos, are encouraged, but not mandatory.
Important Dates:
Dead-line for submission: June 1st, 2011
Notification of Acceptance: July 1st, 2011
Camera-ready papers: August 10, 2011
Evaluation
The correct depiction of the tract displacement, lesion infiltration, as well as false-positive tracts and false-negative findings will be assessed by three experts neurosurgeons. The reliability of the tractography algorithms will be evaluated using bundle overlap and fiber profiles of diffusion properties on the test/retest data.
Datasets
The workshop datasets will consist of 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 header file and a separate uncompressed raw image datafile. The datasets will be provided in the first half of April.
Logistics
The DTI Tractography Challenge workshop will be held on Sunday September 18, 2011 at the Westin Harbour Castle, 1 Harbour Square, Toronto, Canada.
