Figure 2.

Representative 3D-SSP statistical images of AD-like SPECT patterns in (A) early AD in a 69-year-old female; and (B) LPA in a 78-year-old male). (A) Severe relative hypo-perfusion was demonstrated in the bilateral frontal lobes. (B) Relative hypoperfusion mainly in the bilateral temporo-parietal areas with CSF biomarker findings (Aβ42: 290 pg/mL, t-Tau: 803 pg/mL, and p-Tau: 57.8 pg/mL). (A, B) Relative hypo-perfused areas in posterior cingulate cortex and adjacent precuneus were also analyzed.
