Overview
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.
MRI
- [Location] MRI may be helpful in the diagnosis of [disease name]. Findings on MRI suggestive of/diagnostic of [disease name] include:
- [Finding 1]
- [Finding 2]
- [Finding 3]
- Diagnosis of Parkinson disease is mostly clinical but there are some MRI finding supporting the diagnosis.
- In the STN of PD patients there are increased amount of iron. The excess iron will cause a reduction in T2 relaxation time and it’s more prominent in one side.[1] There are also evidence of reduced iron content in putamen and GPe.[2][3]
- 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.[4][5]
- Also we can see atrophy of brainstem and cerebellum in multiple system atrophy.[6][7]
