MRI findings in Parkinson disease are: reduction in T2 relaxation time and reduced iron content in putamen and GPe.
We can also use MRI to differentiate PD from other conditions. for example in the midbrain, thinning of anteroposterior diameter and enlargement of third ventricle in suggestive of supranuclear palsy. Also we can see atrophy of brainstem and cerebellum in multiple system atrophy.
