Huntingtons Disease (HD) is a hereditary genetic disease which presents clinically with motor, cognitive and behavioural symptoms. Single voxel MRS (STEAM, TR/TE/TM = 2000/19/25 ms) was performed in frontal lobe, hypothalamus, thalamus, caudate nucleus (CN) and putamen in 8 gene carriers and 11 healthy controls on a Philips 7 Tesla Achiva system. In CN, patients with Huntingtons disease showed decreased NAA concentration and NAA/Cre ratio. Also, Choline levels in thalamus and mI/Cre ratio in the hypothalamus were elevated in patients. No significant differences between patients and controls were found for metabolite concentrations or metabolite/Cre ratios in putamen and frontal lobe.
