FIG 1. Example of the segmentation procedure for macroscopic CSF and lesions distinct from lacunes.
A, Axial view image of the b0 map from fluid-attenuated data.
B, Mean diffusivity map from fluid-attenuated data obtained before segmentation.
C, Mean diffusivity map from standard data obtained before segmentation.
D, Mean diffusivity map from standard data obtained after segmentation for macroscopic CSF and lesions. The segmentation masks for macroscopic CSF and for lesions were obtained from the fluid-attenuated b0 maps (shown in A).
