DTI Meeting Minutes | October 3, 2006

Present: Sylvain, Katharina, Marty, Marek, Doug, Kate, Marc, Gudrun, Moto, Toshiro, Bum Seok, Gordon, CF

Review from last meeting:

• Moto updated us on his current projects; he is working with Tsuyoshi on a project and Usman is helping him with another.
• The data for Lynn DeLisi's scans have been sent to her since last meeting; she is analyzing the data so we don't have to do anything more for the time being
• Marc finished a working script that can split and measure tracts between ROIs. When he returns from MICCAI we will take a closer look at this and present some sample output.

Fornix tractography

• Kate is doing fiber tracking of the fornix for 8 cases (4 NC, 4 VCFS). Current method works well for majority of cases, but for 2-3 of the cases, no tracts are created for the right fornix.
• This is a difficult region for the 1.5T data; slice thickness may be too big for the posterior curve of the fornix
• Changing tractography settings doesn't help this problem; we will try to smooth the DWIs, and increase the resampling rate of the labelmaps
• Sylvain will meet with Doug and Kate to work out a better method.

3T cases

• Marc has been working on post-processing of new cases; this pipeline should be done by the end of this month.
• Marek will need preliminary data (cingulate tractography) on these scans by the end of the year
