Advances in stereotactic radiosurgery for brain neoplasms

It has been nearly half a century since Leksell introduced brain radiosurgery. In the past decade, the procedure has become widely used as both a primary and adjuvant treatment. Radiosurgery is now commonly employed for arteriovenous malformations, brain metastases, and several benign lesions. Its use in primary brain malignancy remains of uncertain benefit. Improvements in imaging, hardware, and software promise an even greater role for the technique.
