Demyelinating and ischemic brain diseases: detection algorithm through regular magnetic resonance images

[EN] This work presents the advance to development of an algorithm for automatic detection of demyelinating lesions and cerebral ischemia through magnetic resonance images, which have contributed in paramount importance in the diagnosis of brain diseases. The sequences of images to be used are T1, T2, and FLAIR. Brain demyelination lesions occur due to damage of the myelin layer of nerve fibers; and therefore this deterioration is the cause of serious pathologies such as multiple sclerosis (MS), leukodystrophy, disseminated acute encephalomyelitis. Cerebral or cerebrovascular ischemia is the interruption of the blood supply to the brain, thus interrupting; the flow of oxygen and nutrients needed to maintain the functioning of brain cells. The algorithm allows the differentiation between these lesions.The authors are grateful with the Universidad Técnica Particular de Loja Hospital (H-UTPL) for collaborate with the data for this project.Castillo, D.; Samaniego, R.; Jiménez, Y.; Cuenca, L.; Vivanco, O.; Rodríguez-Álvarez, M.
