Dear Victor, Sorry for the slow response. 1.5 T is not a problem. Do you have a companion 1mm T1? If no: then the main problem is the main recon stream. If yes: what is the in-plane resolution and orientation? If it’s a high-res coronal, it may help with the subfields. For the thalamus, I’d just use the 1 mm T1. Cheers, /Eugenio

Hi FS developers,
We were wondering whether a MRI scan that has 2.6 mm thickness + is 1.5 T would be sufficient for a subfield analysis (amygdala, hippocampus, thalamus).
Thanks, Victor Zeng Beth Israel Deaconess Medical Center Keshavan Lab --
