Comparison of Olfactory Tract Diffusion Measures Between Early Stage Parkinson’s Disease Patients and Healthy Controls Using Ultra-High Field MRI

Abstract

This study showed that fiber tracking of the OT was feasible in both early stage PD and healthy controls using 7T diffusion weighted imaging data. However, 7T MRI diffusion measures of the OT are not useful as an early clinical biomarker for PD. Future work is needed to clarify the role of other OT measurements as a biomarker for PD and its different subgroups.
