Head Computed Tomographic measurement as an early predictor of outcome in hypoxic-ischemic brain damage patients treated with hypothermia therapy

Table 2 Assessment of HU values in regions of interest and the gray matter/white matter 2 ratio in GOS 1&2 and 3–5 patients

	GOS 1&2(n = 42)	GOS 3–5(n = 16)	P
*Measurement by our original method*
Cerebral cortex	32.1 (2.9)	36.2 (1.4)	<0.001
White matter 1	29.8 (2.3)	30.1 (1.2)	0.69
DCW	2.2 (1.6)	6.1 (1.4)	<0.001
*Measurement by Torbey et al. method*
Gray matter
Caudate nucleus	34.6 (2.5)	36.7 (1.4)	0.006
Putamen	33.4 (2.5)	35.3 (2.4)	0.21
White matter 2
Posterior limb of internal capsule	30.9 (2.6)	32.4 (1.7)	0.04
Corpus callosum	29.5 (2.5)	30.4 (1.7)	0.21
GM/WM2 ratio	1.12 (0.1)	1.13 (0.1)	0.71

Values are mean (SD). HU, Hounsfield unit; GOS, Glasgow Outcome Scale; SD, standard deviation; DCW, difference in HU values between the cerebral cortex and white matter 1; GM, Gray matter; WM2, White matter 2.
