[Mristudio-users] 2d rois

[Shaimaa Abdelsattar]

Hello experts,
I have one question regarding the degree of accuracy of my data if i performed affine and trilinear normalization of my subjects to a template and then i manually drew a single 2 d roi (5 voxel)  on an anatomical structure e.g. left cerebral peduncle (trying to perform it in the  exact level and location in each patient )  to compare the resulting data among subjects.
Can this approach give a valid data to rely on in comparison 

Thank you for your concern
