We developed a fast and robust method to automatically segment ischemic lesions from a combination of acute diffusion-weighted MRI and apparent diffusion coefficient image volumes. This new segmentation technique extracts the ischemic areas from standard, clinical DWI image volumes of patient (N=40) with acute middle cerebral artery (MCA) stroke symptoms from the La Salptrire stroke center (Paris, France) database.
