Brain Mapping to Plan Safer Radiation for Brain Tumors

This trial is testing whether a noninvasive brain-mapping procedure called navigated transcranial magnetic stimulation (nTMS) can help radiation doctors create more precise treatment plans for patients who have had brain tumor surgery. The technique uses magnetic pulses to identify exactly where your brain controls movement, so doctors can avoid damaging those critical areas when they deliver radiation therapy. This may help protect your ability to move while still treating the cancer effectively.

After surgery for brain tumors near the motor cortex (the part of your brain that controls movement), radiation therapy is important to prevent cancer from returning. However, standard imaging methods can be off by up to 1 centimeter when identifying exactly where motor control happens in your brain, which risks damaging healthy tissue. This trial is testing whether the new brain-mapping technique could give doctors more accurate information, allowing them to create safer, more personalized radiation plans.
