Ciao Luigi, I haven't tried FLAIR for images the subfields, but if you sent me a high-res FLAIR acquisition of the hippocampus, I could take a look. If you are doing T2, you could implement the procotol used in ADNI: coronal slices with 0.4x0.4 in plane resolution, with 2mm slice separation (ideally, you would position the box in an slightly oblique positions such that the coronal slices cut the hippocampus perpendicularly to it major axis). Cheers, Eugenio

Our main concern is to to maximize the information-to-duration ratio of the entire protocol. In order to improve the subfields' segmentation we read that it is better to add a T2 or "other" sequences. Will the FLAIR alone (+T1) can work well as the T2? If instead the T2 is preferable, what is the coarsest-but-still-informative resolution you suggest? Thank you for sharing your experience! Have a nice day, Luigi. _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
