Principles of Stereotactic Radiosurgery for Brain Metastases

Quick fact

Stereotactic radiosurgery can treat multiple brain metastases in a single session with sub-millimeter accuracy, often achieving local control rates above 80–90% for small tumors, while sparing the rest of the brain from radiation exposure.

Why this is interesting

Imagine delivering a lethal dose of radiation to a brain tumor smaller than a pea—without touching a single hair on the patient's head. How can we be so precise?
