Motivation: Huntington’s disease (HD) is characterized by myelin damage and iron accumulation. Robust detection of myelin and iron is critical.
Goal(s): To apply a series of MRI techniques to detect myelin and iron changes in HD.
Approach: A 3D Short TR Adiabatic Inversion Recovery UTE (STAIR-UTE) sequence for Myelin Proton Fraction (MPF) mapping, UTE Quantitative Susceptibility Mapping (UTE-QSM) sequence for iron mapping, divided Subtracted Inversion Recovery (dSIR) sequence for morphological imaging, and synthetic MRI have been applied to HD (n=7) and control (n=7) population.
Results: People with HD show significant myelin loss in white matter and iron accumulation in gray matter over control subjects.
Impact: The STAIR-UTE, UTE-QSM and dSIR techniques can detect myelin loss, iron accumulation, and morphological changes in HD, respectively, and may help with early diagnosis and treatment monitoring of HD.
