Angiographic technique to precede gamma knife radiosurgery for intracranial arteriovenous malformations.

Abstract

Stereotactic radiosurgery of small arteriovenous malformations (AVMs) and certain benign and malignant brain tumors has been used to treat 300 patients at our institution since August 1987. This angiographic technique allows both excellent lesion resolution as well as stereotactic coordinate frame visualization. This technique requires changing our routine diagnostic angiographic methods
