Este artigo descreve um modelo estatístico para análise de dados volumétrico MRI, que identifica o "ponto de mudança", quando começa a atrofia do cérebro em premanifest a doença de Huntington. Cérebro de todo o mapeamento dos pontos de mudança é alcançado com base nos volumes de cérebro obtidos usando um pipeline de segmentação baseados em atlas de imagens ponderadas em T1.
