Fig. 5.

Examples of WM lesion segmentation for a high and a low DICE. The WM lesions are very small and diffuse, so even a slight difference in the overlap can cause a big decrease in the DICE score; (a) and (c) true FLAIR; (e) and (g) predicted FLAIR; (b) and (d) segmentation of WM lesions (red) using true FLAIR; and (f) and (h) segmentation of WM lesions using predicted FLAIR. (Note: for interpretation of the references to color in this figure legend, the reader is referred to the online version of this article.)
