Clinical Applications
Combination of FLAIR and DW imaging with ADC mapping for depiction
of effects of multiple strokes. Axial T2W FLAIR image (A) shows three
areas affected by strokes (arrows). Axial DW-EPI image (B) and ADC
map (C) allow determination of the age of the strokes: The affected
areas of the right frontal operculum and left frontal lobe (single
arrows) show no evidence of restricted diffusion; this finding indicates
that the stroke is old. In contrast, the affected area of the left parietal
lobe (double arrows) appears bright in B and dark in C, evidence of
restricted diffusion indicative of the most recent stroke. The area of
the second most recent stroke, that in the left frontal lobe (single
arrow), appears bright in both B and C; and the area of the oldest
stroke, that in the right frontal operculum (single arrow), appears dark
in B and bright in C.
