Dear experts,
For our study, we are planning on combining two different datasets to examine cortical thickness. There is a slight difference in the inversion time (400 vs 650) and flip angle ( 8 vs 11) between the two datasets. I know that free surfer measurements are fairly consistent across different scanner types and strengths, but do you know if slight differences in mri sequence parameters have an affect on cortical thickness? I was planning on adding it as a covariate in our analysis just in case.
Thank you! Arsenije
