Comparison of Physiological Parameters Between NAWM and Leukoaraiosis

Parameter NAWM (mean ± SEM) Leukoaraiosis (mean ± SEM) % change (mean ± SEM) P-value N
CBF (ml/min/100 ml brain) 33.5 ± 1.9 13.4 ± 2.0 -60.3 ± 5.2 < 0.001 10
CVR (%BOLD/mmHg) 0.066 ± 0.004 0.035 ± 0.009 -47.5 ± 11.6 0.005 10
KBBB (%) 0* 0.42 ± 0.11 N/A 0.003 13
MD(10−3mm2/s) 0.783 ± 0.008 1.151 ± 0.034 47.0 ± 3.9 < 0.001 13
FA 0.400 ± 0.005 0.240 ± 0.009 -39.9 ± 2.2 < 0.001 13
*

In the calculation of KBBB it was assumed that the leakage in NAWM is 0. Thus, this value in the table is 0 for all subjects.
