For more information on identifying white matter tracts using DTIStudio, see http://www.loni.ucla.edu/~narr/protocols.php or the related protocols below.
Note: Tractography shown in this protocol was performed in DTIStudio using 30 direction diffusion data.
First ROI: Identify the coronal slice that crosses the posterior edge of the cingulum. Select all fibers included in the hemisphere of interest. |
Second ROI: Identify the most posterior coronal slice in which the frontal lobe is disconnected from the temporal lobe. Select all fibers in the temporal lobe. * Be sure to remove all fibers that are clearly not a part of the tract. |
