Colleagues,
We are preparing to perform longitudinal pilot studies a group of subjects and controls under far less than ideal conditions. The initial MRI scans were done clinically on a 1.5T Siemens scanner using the ADNI Siemens scanning protocol. The follow-up scans need to be done on a 3.0T Phillips (research, i.e., gratis) scanner using the ADNI Phillips protocol. Am I correct in assuming that the FreeSurfer longitudinal pipeline will somewhat iron out the inherent segmentation & parcellation differences between MRIs taken on these two machines?
Thank you, Alfred Ochs
