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-protocols.pdf Do you know a more detailed version of the ADNI protocol?
In the default Siemens highres hippocampus T2 protocol the 2D distortion correction is turned on, while the distortion correction is turned off in both the default T1 MPRAGE Siemens morphometry protocol and the 1*1*1mm^3 T1 MPRAGE protocol suggested by Andre. Is it problem for hippocampal subfield segmentation if I use distortion corrected highresolution T2 TSE and uncorrected T1 MPRAGE images for the evaluation?
