Cortical lesions in multiple sclerosis are characterized by simultaneous hiperintensity in FLAIR images and hypointensity in T1 images. We have developed a method for automatic lesion detection that includes tissue segmentation correction, lesion detection and quantification. We have evaluated the technique in a study on Multiple Sclerosis, including 21 controls and 15 patients. All subjects were correctly classified with our method. All the algorithms have been included in a plugin for 3D Slicer.
