Axial T2-weighted magnetic resonance imaging 2 days after admission showing small infarctions in the deep white matter and subcortical high-signal intensities in both hemispheres. Diffuse cortical atrophy that is more prominent in the central areas is also demonstrated. Note that neither ischemic nor atrophic changes are present in the basal ganglia.

Brain MRI showed subcortical white matter ischemic changes, marked cortical atrophy that was prominent in the bilateral central areas, and several small infarcts in deep white matter of both hemispheres (Figure 1).
99mTc-ECD SPECT with easy Z-score Imaging System 10 days after admission showing decreased cerebral blood flow in the bilateral central areas that extends to the frontal and parietal areas.

Single photon emission tomography using technetium-99m-L, L-ethyl cysteinate dimer (99mTc-ECD SPECT) showed decreased cerebral blood flow in the bilateral central areas, which extended to the frontal and parietal areas (Figure 2).
