Motor Eloquent Navigated Transcranial Magnetic Stimulation for Radiosurgery Planning
Insel Gruppe AG, University Hospital Bern

INTERVENTIONAL
Conditions
Summary
With this project, the study group wants to investigate whether a postoperative navigated transcranial magnetic stimulation (nTMS) motor map can improve stereotactic radiosurgery (SRS) planning in patients who underwent resection for a brain metastasis near the primary motor cortex. Specifically, the map could allow for more precise location of motor eloquent tissue, thereby minimizing the radiation dose on these areas while preserving high radiation dose on target tissue (i.e. tumor cells).

Interventions
Every patient will undergo a postoperative nTMS motor mapping, and both the "standard" and "nTMS-adapted" SRS plan will be created for every patient. The plan will be selected by the radiation oncologist, depending on whether at least 95% of the dose is administered to the target volume with the "nTMS-adapted" plan or not. Every patient then receives SRS.
