We utilized multi-contrast UHF MRI to accurately characterize longitudinal changes in hippocampus subfield volumes. Our automatic pipeline (LASHiS) is openly available and compares favorably to both cross-sectional and other longitudinal methods.

Fig. 2. Hippocampus subfield segmentation results (coloured) for a single representative subject for the five tested methods at the same slice in a coronal view. Each segmentation result is overlaid on the high-resolution T2w scan save for FS Long, which utilises a T1w scan for segmentation. Green arrows denote a possible under-segmentation, orange for a possible over-segmentation of a subfield where subfield information is not available
