P08-Diffusion kurtosis imaging detects early microstructural changes in dorsal motor nucleus of vagus in intragastric rotenone mouse model of Parkinson’s disease

The aim was to determine whether diffusion kurtosis imaging (DKI-MRI) could detect changes in dorsal motor nucleus of vagus (DMV) in mice who received chronic administration of rotenone. This may help in early diagnosis of patients with Parkinson's disease.Mice received vehicle (VEH) or rotenone (ROT) intragastrically for 4 months. DKI scanning was performed at 2, 3 and 4 months. ROI analysis was used to compare kurtosis and diffusivity parameters in GM regions. WM tracts were investigated using the tract-based spatial statistics.
