Summary

This study tests whether a new, high-field 3T MRI technique can more accurately pinpoint the subthalamic nucleus — a key brain area targeted during deep brain stimulation (DBS) for Parkinson's disease. Researchers will compare images from the new method with standard 1.5T MRI in 105 Parkinson's patients who are candidates for DBS. The goal is to improve surgical precision, which could lead to better symptom relief and fewer side effects.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could improve the precision of deep brain stimulation surgery for Parkinson's, potentially leading to better symptom control and fewer side effects.
What could go wrong: This is an early imaging study, not a treatment trial. The new MRI method may not prove more accurate than current techniques, and any benefit to patients remains uncertain.
