Fig 1. Mismatch Method 2. DWI sequence (A) is contrasted to maximize the lesion conspicuity (B) and its intensity values are inverted (C) and then blended with the registered MTT sequence (D). Mismatch Method 1 (E): separate lesion measurements on DWI and MTT sequences compared with Mismatch Method 2 (F): single measurement of the blended difference. Mismatch Method 1 (G): separate lesion measurements on DWI and MTT sequences compared with Mismatch Method 2 (H): single measurement of the blended difference with an arrow indicating the larger MTT lesion seen on the blended map.
