Questo articolo descrive un modello statistico per analisi di dati di MRI volumetrica, che identifica il "punto di svolta" quando l'atrofia del cervello inizia in pre malattia di Huntington. Intero-cervello mapping dei punti di cambiamento viene realizzato sulla base dei volumi di cervello ottenute tramite una pipeline di segmentazione basata su Atlante delle immagini di T1-weighted.
