Brief summary
Deep brain stimulation (DBS) is an effective treatment for a variety of neurological and psychiatric disorders, with more than 200,000 patients implanted with DBS devices worldwide. Parkinson's disease is one of the typical indications.The clinical outcomes of DBS depends on the accurate implantation of the lead, and the identification of the lead locations is the basis for evaluating the effectiveness of the treatment. The aim of this study is to localize the implantation position of the lead based on postoperative MRI images and to reconstruct the relative spatial relationship between the lead and the stimulation target. By comparing with the lead position identified based on postoperative CT, this study will evaluate the accuracy of identifying the DBS lead position directly from MRI. This study may help to optimise the stimulation parameters and investigate the best stimulation targets for DBS patients.
Interventions
DIAGNOSTIC_TESTMRI and CT scan
An MRI scan of the head in about 30 minutes. During the scan, MRI thermometry will be performed to monitor for possible lead heating due to the interaction of the MRI radiofrequency field and the implanted devices. An CT plain scan of the head in about 10 minutes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Lead position | 1 day | The accuracy of the lead localization will be evaluated by the distance between the identified position of the lead electrode and the center of the reconstructed stimulation target. The result of lead localization by CT will be used as the reference. |
