TABLE 4.

Mean CBF values (mL/100 g/min) and their standard deviations in gray matter ROIs that showed significant metabolic differences between groups

ROI	TBI group	Controls	t	df	P value
ROI	Mean (SD)	Mean (SD)	t	df	P value

R putamen	46.177 (14.912)	51.508 (8.754)	0.900	17	.380
R hippocampus	58.218 (16.743)	59.989 (7.918)	0.276	17	.786
L anterior cingulate	56.649 (18.847)	72.172 (12.373)	2.026	17	.059
R posterior cingulate	53.857 (13.708)	58.301 (9.246)	0.792	17	.439
L posterior cingulate	64.241 (20.441)	64.304 (8.606)	0.008	17	.994

Note: T-values and P values are from independent-samples t-tests comparing the CBF group means. TBI group: n = 11; control group: n = 8.

Abbreviations: CBF, cerebral blood flow; ROI, region of interest; TBI, traumatic brain injury.
