Table 2.

Mean ± s.d. of CBF, CBV, and MTT values averaged over the normal-appearing white matter and over the deep gray matter nuclei of healthy controls, RR-MS, and PP-MS patients

	Healthy controls		RR-MS patients		PP-MS patients

	Deep GM	WM	Deep GM	NAWM	Deep GM	NAWM
CBF (ml/100 g/min)	68.2±7.1	42.4±5.9	62.9±7.8	32.7±4.9	57.2±8.4	27.3±4.5
CBV (ml/100 g)	4.8±0.6	3.1±0.7	4.5±0.7	2.4±0.5	3.9±1.0	1.9±0.6
MTT (seconds)	4.3±0.6	4.4±0.7	4.3±0.7	4.3±0.6	4.0±0.9	4.2±1.0

CBF, cerebral brain flow; CBV, cerebral brain volume; GM, gray matter; MTT, mean transit time; NAWM, normal-appearing white matter; PP-MS, primary-progressive multiple sclerosis; RR-MS, relapsing-remitting multiple sclerosis; s.d., standard deviation; WM, white matter.

Values are given as means ± s.d. and adjusted for age, gender, and disease duration.
