The distribution of FVHs in four subgroups

	FVH within DWI lesion	FVH beyond DWI lesion	FVH (both within and beyond)
Total patients, n=100, (%)	14 (14.0)	73 (73.0)	13 (13.0)
BZ group, n=29, (%)	1 (3.4)	26 (89.7)	2 (6.9)
ML group, n=39, (%)	0 (0)	38 (97.4)	1 (2.6)
LT group, n=26, (%)	13 (50.0)	3 (11.5)	10 (38.5)
SL group, n=6, (%)	0 (0)	6 (100)	0 (0)

BZ group, border-zone infarct group; DWI, diffusion-weighted imaging; FVH, fluid-attenuated inversion recovery vascular hyperintensity; LT group, large territory infarct group; ML group, multiple lesion infarcts group; SL group, single cortical or subcortical lesion group.
