1. Dopamine transporter imaging is valuable in monitoring Parkinson’s disease progression.
2. Decline in dopamine transporter signal in the less affected putamen is associated with worsening motor function.
3. Higher age and longer disease duration are linked to more severe motor symptoms.
4. Average annual increase in MDS-UPDRS-III scores was approximately 2.4 points.
5. The study findings emphasize the potential for personalized disease tracking and intervention testing.
6. Future research is expected to refine the role of dopamine transporter imaging in guiding personalized monitoring and treatment strategies.
