External Email - Use Caution
Dear FreeSurer experts,
we recently did a simultaneous measurement of MRI and EEG in adolescent patients with obsessive-compulsive-disorder. Due to the electrode gel we see image artifacts mostly in parietal and frontal regions (please see attached images).
Has anyone experience with these kinds of measurements? Is there a way to fix the artifacts? We are worried that the calculation of eTIV will also be corrupted and we cannot use it to correct for head size in the subcortical structures (which are our ROIs, mostly striatum).
Thanks a lot for any advice!
