sectional images of the right hippocampus in a normal and AD subject; so, stratum oriens; DG, dentate gyrus; sub, subiculum; scale bar 1 mm). The CA1-SRLM exhibited more thinning than the CA1-SP in AD compared to NC (p 1⁄4 0.003 vs 0.8) (Figure 2: SRLM and SP thickness was measured as illustrated in each individual, averaged over the left and right, and normalized to TIV). Raw, non-normalized measurements revealed the same finding. In addition, hippocampal volume was no different between the groups (p 1⁄4 0.15). Conclusions: Hippocampal CA1 neuropil atrophy, visualized in vivo using 7T MRI, may be a more reliable marker of mild AD than changes in other areas of the hippocampus. These findings validate pathological predictions, possibly providing an objective in vivo biomarker for mild Alzheimer disease.
