We are attempting to analyze archival MRI data obtained during routine clinical care. Unfortunately, the standard clinical MR sequences do not include 3D volumes. Will the freesurfer algorithm work on slice data so that each slice could be marked with the pial and white matter boundaries? Then, the next question is how to apply seg and parc templates to analyze correctly defined subcortical structures, and cortical regions? Has anyone tried to do this type of archival data analysis? Unfortunately, our standard sequences do not include 3D volumes, so to do the retrospective work we’ll need a workaround.

 

Thank you.
