1 Focal atrophy in dementia with Lewy bodies on MRI: a distinct pattern from Alzheimer's disease by Jennifer L. Whitwell, Stephen D. Weigand, Maria M. Shiung, Bradley F. Boeve, Tanis J. Ferman, Glenn E. Smith, David S. Knopman, Ronald C. Petersen, Eduardo E. Benarroch, Keith A. Josephs, and Clifford R. Jack Brain Volume 130(3):708-719 March 8, 2007 © 2007 The Author(s)‏

2 Coronal slices of the unsmoothed customized template image showing the location of the four ROI used in the VBM-based ROI analysis. Jennifer L. Whitwell et al. Brain 2007;130:708-719 © 2007 The Author(s)‏

3 Three-dimensional surface renders showing the patterns of cortical GM loss in the DLB, and Alzheimer's disease groups, compared with controls (corrected for multiple comparisons, P < 0.05). Jennifer L. Whitwell et al. Brain 2007;130:708-719 © 2007 The Author(s)‏

4 Patterns of GM loss in the DLB and Alzheimer's disease groups compared with controls (corrected for multiple comparisons, P < 0.05), overlaid on the unsmoothed customized template. Jennifer L. Whitwell et al. Brain 2007;130:708-719 © 2007 The Author(s)‏

5 Regions showing significantly greater GM loss in the Alzheimer's disease group than the DLB group (corrected for multiple comparisons, P < 0.05), overlaid on the unsmoothed customized template. Jennifer L. Whitwell et al. Brain 2007;130:708-719 © 2007 The Author(s)‏

6 Box-plots of each patient's average VBM-based modulated GM density per voxel for four ROI. The horizontal lines of the boxes represent the 25th, 50th (median) and 75th percentiles of the distributions. Jennifer L. Whitwell et al. Brain 2007;130:708-719 © 2007 The Author(s)‏

7 Box-plots showing the hippocampal and SI volumes measured from the volumetric MRI for each subject. Jennifer L. Whitwell et al. Brain 2007;130:708-719 © 2007 The Author(s)‏

8 Schematic diagram showing the location of cholinergic, serotonergic and noradrenergic neurons in the brainstem and basal forebrain. Jennifer L. Whitwell et al. Brain 2007;130:708-719 © 2007 The Author(s)‏
