Tractography Study Telephone Conference Nov 16 2007
Minutes from T-con November 16 - 2 PM EST/ noon MST
Attendees: CF Westin, Ron Kikinis, Tom Fletcher, Casey Goodlett, Sylvain Gouttard, Vince Magnotta, Jeremy Bockholt, Tri Ngo, Sonia Pujol, Sylvain Bouix, Anastasia Yendiki, Randy Gollub (others I missed?)
- Agreed to go forward with the MIND Reliability data set and use of Freesurfer white matter segmentation masks (and complete Freesurfer segmentation) to be provided by Randy Gollub/Jeremy Bockholt
- Adjustments to dataset: remove measurement frame information
- CF to make xythos account for holding the raw and processed tractography results data generated by all groups
- Sonia/Randy to provide all ROIs and indicate source/sink for them
- All data to be posted on SRB/xythos by November 26th
- All ROIs to be posted on SRB/xythos by November 30th- 1st set done by November 30th
- All sites to download and test first case and give feedback re: preprocessing and ROI problems as well as provide exemplar results by December 7th
- All sites to upload full results by December 14th
- Slide presentations of results and planning of next step in project Wednesday January 9, 2008 at the AHM (see http://www.na-mic.org/Wiki/index.php/2008_Winter_Project_Week_Tractography)
UPDATE ON DATA PROCESSING November 30, 2007
- Unfortunately the first visit of case M02100023 is missing the phase and magnitude maps, so no EPI distortion correction can be done. Thus, we have n= 9 test-retest w/EPI distortion correction, n=10 w/EPI distortion correction for single session comparability between algorithms.
- The first set of ROIs (for case M02100024_visit1) is now ready, and it includes the following tracts: the Cingulum cingulate gyrus (left & right), the Cingulum Hippocampal (left & right), the Uncinate Fasciculus (left & right), the Fornix, the Corpus Callosum - Forceps Major, the Corpus Callosum - Forceps Minor and the Internal Capsule (left & right).
Marek suggested that we not include the Arcuate Fasciculus based on the poor outcomes that all the tractography algorithms - except for the Stochastic tractography method- demonstrated during the Santa Fe meeting. If anyone feels strongly that this should be included, reply all and we will work to add it.
