Brain Network Alterations in Alzheimer’s Disease Identified by Early-Phase PIB-PET

Table 2

Two sample t-test results of the highest correlated component pair of ¹¹C-pPIB and ¹⁸F-18F-FDG between AD and CN and between MCI and CN groups.

AD versus CN				MCI versus CN
^11C-pPIB		^18F-FDG		^11C-pPIB		^18F-FDG
value	T value	value	T value	value	T value	value	T value
0.0010	−3.6907	0.0002	−4.3774	0.0009	−3.7993	0.0010	−3.7279

AD: Alzheimer’s disease; MCI: mild cognitively impaired; CN: cognitively normal; ¹¹C-pPIB: (¹¹C)-labeled Pittsburgh Compound B; ¹⁸F-FDG: fludeoxyglucose F 18.
