Identifying the cingulate gyrus component of the cingulum in DTIStudio using a multiple ROI approach


Written 7/25/08 by Aimee Zisner. Updated 02/17/2009 by Owen Phillips. Email Dr. Katherine Narr if you have any questions. This protocol explains how to identify the cingulate gyrus component of the cingulum in DTIStudio. For more information on identifying white matter tracts using DTIStudio, see http://narr.bmap.ucla.edu/protocols/.

 

Note: Tractography shown in this protocol was performed in DTIStudio using 30 direction diffusion data.

 

To identify the cingulate gyrus component of the cingulum (CGC):

First ROI First ROI: Identify the coronal slice intersecting the middle of the splenium of the corpus callosum using the mid-sagittal slice. Select all fibers superior to the corpus callosum on the side of the hemisphere of interest.
Second ROI: Identify the most central coronal slice of the corpus callosum using the mid-sagittal slice. Select all remaining fibers superior to the corpus callosum.

* Be sure to remove all fibers that are clearly not a part of the tract.
