Group comparisons of resting state CBF and CBF and BOLD response to picture encoding by cognitive status

CN, n = 29
mean (sd)		 MCI, n = 16
mean (sd)		 t p Cohen’s d
Bilateral MTL Resting State CBF 65.98 (24.80) 49.69 (19.87) 2.23 0.03 0.72
Bilateral MTL Percent Change CBF 100.58 (62.60) 91.67 (61.92) 0.44 0.67 0.14
Bilateral MTL Percent Change BOLD 0.56 (0.24) 0.63 (0.27) 0.92 0.36 0.27

CBF = cerebral blood flow; BOLD = blood oxygenation level dependent; CN = cognitively normal; MCI = mild cognitive impairment; MTL = medial temporal lobe. Degrees of freedom for all t-tests = 43.
