FOR BRAIN TUMORS
Stereotactic radiosurgery allows the radiation oncologist and neurosurgeon to work together to focus a high dose of radiation precisely on a small target lesion within the brain. It is used to treat brain metastases, arterial venous malformations, gliomas, astrocytomas, meningiomas, acoustic neuromas, pituitary adenomas, and craniopharyngiomas.
Stereotactic radiosurgery is a one-day outpatient procedure. It first involves rigid screw fixation of a localization frame to the patient's head. Next a detailed CT scan of the head is performed with the frame in place. These CT images are imported into the treatment planning computer and the target lesion carefully identified and outlined. Precise detailed treatment planning then follows. The final treatment plan will allow delivery of a high dose of radiation just to the target lesion, while sparing the remainder of the brain.
The single, high dose radiation treatment is then delivered in the radiation oncology department. Treatment takes approx. 30 minutes and is completely painless. Once completed, the localization frame is removed and the patient is ready to go home.
