The objective of this pilot study was to assess white matter (WM) microstructural integrity in pre-clinical models of Parkinson’s disease using fractional anisotropy (FA) from diffusion tensor imaging (DTI). We assessed changes in FA in parkinsonian rats with levodopa-induced dyskinesia both over time and compared with control (sham) rats.
