Paired T1-weighted and T2-weighted MRI scans at 3 T and 7 T acquired for a subject (sub-10), the left hippocampus of the subject was shown for multiple views and multiple modalities. The final two rows depict zoomed-in coronal views of the hippocampus from head to body at three different slices, comparing 3 T and 7 T T2-weighted images. The 3 T images show lower resolution and significant partial volume effects, while the 7 T images, with enhanced resolution, more clearly demonstrate the hippocampal internal architecture, outer boundaries, and inner boundaries between subfields, with the hypointense line appearing more consistent and visible compared to 3 T.
