Q: What is Gamma Knife Radiosurgery?
The Model C Gamma Knife is the most sophisticated version of a 20-ton device which uses radiation beams rather than traditional neurosurgical instruments to successfully treat a variety of neurological problems. Gamma knife radiosurgery is safe, effective and non-invasive treatment for tumors and vascular malformations of the brain, as well as certain functional disorders. Unlike conventional surgery, treatment with the Gamma Knife requires no surgical incision and causes minimal patient discomfort. Prolonged hospital stays for recovery from radiosurgery are not required.
Gamma Knife radiosurgery can treat brain tumors and vascular malformations while sparing adjacent healthy, normal brain tissues. This is due to the ability of the Gamma Knife to focus a large number of radiation beams on a precisely defined target volume.
Because of the very rapid fall-off a radiation does outside the target volume with radiosurgery, the surrounding brain tissue receives very little radiation exposure. This extreme localization of radiation does to within the target volume greatly reduces the risks of Gamma Knife radiosurgery compared to vocational radiation treatment or brain surgery.
Gamma Knife Radiosurgery can successfully treat a variety of brain diseases, including both primary and metastasis tumors. Specific indications for radiosurgery include:
۰Gliomas to include low grade astrocytomas to anaplastic astrocytoma to
glioblastoma, oliogodendroglioma, ependymoma, and pilocytic astrocytoma.
۰Pineal tumors and craniopharyngioma
Gamma Kinfe radiosurgery is a highly effective, non-invasive alternative to conventional surgery for a number of neurological problems. Patients experience very little discomfort. Only local anesthesia is necessary, eliminating the risks associated with general anesthesia required for many neurosurgical procedures.
Gamma knife radiosurgery is significantly safer than conventional brain surgery. It has been used to treat over 150,000 people worldwide and has shown to significantly reduce morbidity associated with open procedures.
Treatment with the gamma knife may complement conventional radiation therapy for brain tumors. Since the radiation dose is precisely localized to the tumor volume with radiosurgery, a concentrated "boost" dose of radiation can be given in conjunction with conventional radiotherapy. This increases the probability of tumor control and limits radiation exposure to healthy surrounding brain tissue.
Gamma Knife radoisurgery costs no more than conventional brain surgery. with significantly reduced time required for patient care and recovery in the hospital. Patients can return to pre-surgery type activities within a much shorter period of time than conventional surgery.
