Summary of data from the ten included patients. Example of diffusion weighted imaging – fluid attenuated inversion recovery (DWI-FLAIR) match (A) and mismatch (B). The DWI images are with b-value 1000. The apparent diffusion coefficient (ADC) maps are also displayed. The FLAIR image in B also illustrates the common problem with motion artifacts in these patients. The images in A are from patient 5 and the images in B from patient 6.
