FIG 8. MR images in a 45-year-old man (control subject).

A, Multishot diffusion-weighted coronal image clearly shows the inner structure of the left hippocampus: the subiculum (left arrowhead), CA1 of the hippocampus proper (right arrowhead), CA3–4 (small arrow), and the superficial medullary lamina (large arrow).

B, T2-weighted coronal image faintly shows the superficial medullary lamina (arrow) as a hypointense area.

C, T1-weighted 3D volumetric SPGR image (26/4.3; FOV, 18 cm; matrix, 256 x 256; thickness, 0.8 mm; slab, 64 mm) shows the superficial medullary lamina (arrow) as a hyperintense area and depicts it more faintly than does the T2-weighted image.
