FIG 3. Comparison of signal intensities on diffusion-weighted images with ADC values on ADC maps. Each coordinate of regions of interest in the ADC maps is the same as that in diffusion-weighted images. ADC values are reduced in regions with high signal intensity on diffusion-weighted images (regions 3 and 4 in each patient). Asterisks denote regions in affected cortex identified by high signal intensity on diffusion-weighted images.
