Fig 1. Hippocampal Asymmetry.

Fig 1

(A) Patient 19 –clockwise from top left: A low resolution localizer indicating the coronal-oblique slice thorough the hippocampus shown; 7T: MP2RAGE UniDen reconstruction visualizing the cavity; 7T:T2 TSE image showing a coronal oblique slice through the hippocampus and a visualization of the parenchymal cavernoma; 3T: T2 TSE scan, acquired previously, showing the location of the lesion. On the 3T image, the lesion was less conspicuous and therefore went undiagnosed despite being identified in a retrospective examination of the image; SWI axial slice where the cavernoma can be clearly identified. (B) Patient 24—from top left: A 7T FLAIR image showing relatively equivalent signal intensity in both hippocampi; 7T:T2 TSE image showing full coronal-oblique slice and right hippocampal sclerosis, and 3T T2 images showing the hippocampus.7T:T2 TSE slice series showing a coronal oblique slice through the hippocampus showing right hippocampal sclerosis with decreased digitation and lamination without accompanying signal change in the hippocampus on the FLAIR image. The 3T T2 images for this subject do not show this architectural change in the hippocampus.
