White matter abnormalities have been extensively investigated in Parkinson disease (PD). Diffusion tensor imaging (DTI) studies have reported diffusion abnormalities in the cerebral white matter in patients with PD, but these findings are controversial. The aims of this preliminary study were to investigate how the white matter is altered in PD as measured with DKI and to compare this to what is shown with DTI. DKI can detect changes in the cerebral white matter of PD patients more sensitively than conventional DTI. DKI may enable improved monitoring of disease progression and more effective treatment planning.
