Dear all,
1. Which is the suggested resolution for hippocampal subfields segmentation with freesurfer? I've seen articles with 0.5*0.5*0.5mm^3 and with 1.0*1.0*1.0mm^3 as well. Does the hippocampal subfields segmentation really work with 1.0*1.0*1.0 resolution? 2. The article "Automated Segmentation of Hippocampal Subfields from Ultra-High Resolution In Vivo MRIhttps://surfer.nmr.mgh.harvard.edu/pub/articles/VanLeemputHippocampus2009.pdf." suggested on Freesurfer's page uses FOV=448. We are unable to set up the matrix to achieve 0.38mm resolution using this FOV. Is there any other suggested article to set up our measurements?
Thanks,
Dear Gabor, the segmentation benefits to some extent from higher resolution data, but produces decent estimates of the subfields at 1x1x1. We are working on a new atlas that will incorporate much more detail, and will more effectively take advantage of high-resolution images. Kind regards, Juan Eugenio Iglesias
