This image demonstrates the overlap (grey) between the atrophy in white matter in 9 patients with anosmia for less than 1 year (black) compared with 10 patients with anosmia for more than 1 year (white). The level of significance of the voxel-based morphometry results is p<0.001 and images overlay onto the average T1 image of all subjects. The top row shows one coronal slice and three axial slices, whereas the bottom row shows two coronal slices and two sagittal slices.
