According to Bruce's request I repost the rest of thread: We set up our our hippocampal subfield T2 protocol based on the ADNI protocol (with some minor differences) as suggested by Iglesias. However, we see an artefact similar to the image found in ADNI2 training manual (page 28): http://adni.lon

: [Freesurfer] MRI protocol for hippocampal subfield segmentation Dear Eugenio, The ADNI protocol is quite similar to the default Siemens highres hippocampus protocol, however I haven't find a more detailed version of this one: http://adni.loni.usc.edu/wp-content/uploads/2017/07/ADNI3-MRI-protocol

Hi Gabor, A good place to start is ADNI’s high-res hippocampal T2 protocol. You can find the details on their website. It’s a coronal, anisotropic acquisition of a slab covering the hippocampus (0.4mm in plane, 2mm thickness, 25-30 slices). I’ve been playing a bit with more isotropic acquisition
