Unfortunately the excessive motor abnormality such as chorea yields the acquisition of diffusion magnetic resonance imaging unfeasible in a clinical setting. The diffusion MRI with compressed sensing demonstrated reduced motion sensitivity and improved susceptibility related artifact because of the accelerated acquisition. Because of the reduced acquisition time, diffusion MRI in patient with Huntington Disease would be possible. It is therefore expected that the macromolecule deposition in the brain of patients with HD can lead to detectible changes in diffusion properties. The accelerated diffusion MRI techniques will be used to acquire data from healthy volunteers and patients with Huntington disease. The aim of the study is to develop and optimize a novel accelerated diffusion Magnetic Resonance Imaging (MRI) technique using advanced compressed sensing techniques. The joint sparsity constraint algorithm will be implemented in an in-line reconstruction platform for the diffusion MRI processing.
