Is The Gamma Knife Radiosurgery Effective?
Gamma Knife CenterOver 70,000 patients worldwide have chosen Gamma Knife Radiosurgery for treatment of benign tumors such as acoustic neuromas, meningiomas, pituitary adenomas, pineal tumors; malignant tumors like metastatic tumors, astrocytomas and glioblastomas. The Gamma Knife has also been used to eradicate arteriovenous malformations (AVM) and treatment protocols are under investigation for certain functional disorders such as epilepsy, chronic pain, trigeminal neuralgia, and Parkinson's disease.
Related QuestionsWhat Is Gamma Knife Radiosurgery?
Gamma Knife CenterGamma Knife (a registered trademark of Elekta Radiosurgery of Atlanta, GA) Radiosurgery replaces the surgeon's scalpel with a single, high dose of gamma radiation. Like the surgeon's scalpel, the Gamma Knife eradicates the diseased area with a safe and effective approach. The patient wears a lightweight head frame that attaches to a helmet, through which 201 beams of gamma radiation precisely focus at a single target.
Related QuestionsHow Is Gamma Knife Radiosurgery Performed?
Gamma Knife CenterAfter administering local anesthesia and intravenous sedation, a stereotactic frame is attached to the patient's head. Next the head is imaged using a CT or MRI scanner while the patient wears the stereotactic frame. For vascular malformations, an angiogram is obtained as well. A treatment plan is developed by computer using the brain images. This is done by the coordinated efforts of the neurosurgeon, radiation oncologist and radiation physicist.
Related QuestionsIs Gamma Knife radiosurgery safe?
Q&A Sessions - Astrocytoma | Penn Gamma Knife CenterMore than 30,000 patients safely undergo Gamma Knife radiosurgery each year. The method has been used worldwide since 1968. Gamma Knife radiosurgery allows patients to quickly return to their normal routines. In most cases, only a single procedure is necessary. Our experienced Pennsylvania Hospital Gamma Knife team provides patients with maximum safety and efficacy.
Related QuestionsWhat Are The Advantages Of Gamma Knife Radiosurgery?
Frequently Asked Questions (FAQs)Gamma Knife surgery is different from conventional radiation therapy of the brain because it is only directed to the target and spares unnecessary treatment of adjacent, normal brain. It differs because only a one day treatment is required rather than many treatments over several weeks and can be repeated if needed. It can be used in conjunction with conventional surgery as a boost and can be used in previously inoperable cases.
Related QuestionsIllinois Gamma Knife Center: For PatientsThe Gamma Knife is a treatment unit designed to deliver a highly conformal dose of radiation therapy to intracranial sites using 201 convergent beams emanating from cobalt-60 radiation sources. The Gamma Knife was invented by Drs. Leksell and Larson and the first clinical work was done in 1967 at the Karolinska Institute in Stockholm, Sweden.Related Questions
Who Determines If Gamma Knife Radiosurgery Is Appropriate?

Related QuestionsHow does the Gamma KnifeŽ work?
Gamma Knife - Frequently Asked Questions (FAQ) | Cooper Univ...The Gamma Knife Perfexion? precisely focuses 192 beams of gamma radiation on a specific target area of the brain, with each beam originating from a slightly different point. Highly sophisticated computer software is used to determine the size, location and shape of the area to be treated. Only at the point where all 192 beams cross is enough radiation delivered to affect the diseased tissue, while sparing surrounding tissue.
Related QuestionsWho can be treated with the Gamma Knife?
Gamma Knife - Frequently Asked Questions (FAQ) | Cooper Univ...This noninvasive technology treats patients with abnormalities that are located within the brain or that are too close to delicate structures and blood vessels (though it is most effective on targets less than four centimeters in size). Almost a third of all the patients treated with the Gamma Knife since 1968 have sought relief from blood vessel problems (i.e. AVMs). Nearly two-thirds were treated for brain tumors, including cancer, glial tumors and rarer types of tumors.
Related QuestionsWhy is it called the Gamma Knife if there are no incisions made?
Gamma Knife - Frequently Asked Questions (FAQ) | Cooper Univ...The individual beams of gamma radiation are not strong enough to damage any tissue as they travel through the skull to the treatment site. At the site, the beams join together pecisely to act in the same way a surgical "knife" would to treat the abnormality.

Ear Institute of Chicago: Gamma Knife Radiosurgery-What to e...After patients arrive at the Gamma Knife Center they are given a mild sedative (children are often completely anesthetized). Shortly after that time, a box-shaped head frame is attached to the head with four screws (two in front and two in back). The key to the gamma-knife's precision lies in this box-shaped frame. The frame serves two purposes: 1. It holds the patient's head perfectly still when radiation is given. 2.

Ear Institute of Chicago: Gamma Knife Radiosurgery-What to e...Drs. Battista or Wiet (i.e. a neurotologist), a radiation oncologist and a physicist are the three team members that are involved with designing the treatment plan on day of the procedure. Each of these three different team members has expertise in specific areas related to the treatment. The neurotologist has special expertise in the anatomy and physiology of the anatomical area to be treated.
Related QuestionsWhat is meant by "cure" in Gamma Knife Radiosurgery?
Ear Institute of Chicago: Gamma Knife Radiosurgery-What to e...The cure of a brain tumor by radiosurgery means that the tumor loses its ability to grow and remains the same size, never growing again. The intensely focused gamma rays destroy the ability of the cells to divide. Sometimes benign tumors actually shrink over time and malignant tumors may completely disappear. This curative process occurs over months to years.
