Figure 1. Definition of the hippocampal plane in MRI. The yellow
arrow indicates the horizontal axis of the hippocampal plane, and the
blue arrow its coronal plane. Axial MRI and PET slices were recorded along
the axial hippocampal plane in a patient with left mesial temporal lobe
epilepsy, and the coronal MRI slice was recorded in the same patient who
also had left hippocampal sclerosis.
