[Mristudio-users] corpus callosum morphometry

[Shmuel Miron Dr]

Dear Dr Ihssan

 

I am interested in the same questions in MS patients.

To obtain the midline image we first perform a sagittal 3D FSPGR
anatomical MRsequence (high resolution-voxel size 1x1x1mm)

Now you have 2 possibilities 

1.	use an axial localizer during EPI acquisition to obtain axial
images and the localizer passes through the inferior border of the
splenium and rostrum of the corpus callosum. Then, DTI studio recreates
the Sagittal view that can be used for further analysis. 
2.	use a sagittal localizer as in the attached image to obtain
sagital EPI axquisition  that will give you a good resolution

of the CC that will work in DTI studio 

 

Do you have a suggestion on how to perform a subregion analysis on DTI
studio ?

Dear All,

I want to measure the FA values of subregions of the corpus callosum
using DTI studio, could you please tell me how to obtain the midline
sagittal image of the brain, how to rotate the image? Shall I extract it
to another program?

Many thanks,
