CS-131 for Operable Intracranial Neoplasms
Dr. Kotecha: Radiation therapy can be delivered to the brain externally through machines, which is called external beam radiation therapy. This is the most common approach or use in radiation therapy and some terms that you may hear that are using this type of treatment are stereotactic radiosurgery. An alternative means of delivering radiation therapy is when radiation is actually implanted into the brain itself, and that is called brachytherapy.
