VBM analysis for assessment of atrophic changes in AD patients. Comparison with preserved concentration showed many regional decreases in the AD group (a); however, if the differences of the whole brain size were corrected (preserved amount), only a few regions showed differences including the posterior part of the bilateral hippocampus (red circle, peak-level P < 0.001, cluster-level Puncorr < 0.05) (b)
