Radiation Therapy (RT) for Parkinson's Disease (PD)

Ultra-low Dose, DaT-SPECT-guided Radiation Therapy for the Treatment of Parkinson's Disease

Source: ClinicalTrials.gov · Last updated 16 Jun 2026

Brief summary (registry, in English)

The purpose of this study is to investigate the use of ultra-low, anti-inflammatory doses of radiation therapy (RT) for the treatment of Parkinson's Disease (PD). In this study, the TrueBeam LINAC utilizes a linear accelerator (LINAC) for the delivery of radiation therapy. Dynamic conformal arc (DCA) therapy will be used to deliver a total of five (5) once-a-day radiation treatments (RT) using DaT-SPECT (Dopamine Transporter-Single-Photon Emission Computed Tomography) and MRI imaging to guide radiation treatment planning.
