Gamma Knife radiosurgery is used to treat many types of tumors and lesions in the brain. It can also be used to treat vascular malformations and movement disorders. Using a stereotactic radiosurgery device, gamma knife delivers precise beams of high-dose radiation to the target area. It treats diseased tissue without affecting healthy tissue nearby. The Gamma Knife can be used to treat brain tumors, vascular malformations and other conditions that would otherwise require surgery. It can be used as a single treatment or in combination with other forms of radiation therapy and chemotherapy. One of the biggest advantages of gamma knife radiosurgery is that it has a high success rate and can help improve patient outcomes for many different types of cancers. It is also a safe and effective alternative to conventional surgery, which can have long recovery times. Gamma knife radiosurgery can be used to treat tumors located deep within the brain, as well as in the skull. Gamma knife delivers 192 low-dose beams of radiation intersecting at the tumor. The Gamma Knife is also more efficient than other types of radiosurgery, such as CyberKnife, as all imaging and treatment plans happen on the same day. This is helpful as it allows doctors to keep track of changes in the tumor and minimizes any delay caused by waiting for imaging to be completed. Vascular malformations are a category of abnormalities that involve blood vessels. These can include arteries, veins or lymphatic vessels. They can be found anywhere in the body, whereas they must be treated by a specialist if they are located within the brain. The normal way for blood to move through the body is by travelling through thin walls called capillaries. Then it flows through venules, which join to form veins. A vascular malformation occurs when these blood vessels don’t form properly. These blood vessels can prevent enough oxygenated blood from reaching the capillaries. Neurosurgeons can treat vascular malformations with Gamma Knife stereotactic radiosurgery. The technique is very precise and can target vascular malformation without harming nearby healthy tissue. Treatment is usually done in an outpatient setting and does not require a hospital stay. This is a great option for patients with a small AVM or AVM that’s too large for surgical resection. There’s also less risk of post-treatment swelling and side effects with gamma knife than with surgery. Gamma Knife radiosurgery is ideal for treating small tumors or blood vessels that can't be reached by surgical techniques, and it is especially useful when surgery is not an option. The Gamma Knife uses advanced diagnostic imaging to target the diseased area. The system delivers 192 precisely focused beams of gamma radiation to treat the diseased area. The gamma knife can also be used to treat brain aneurysms. Endovascular therapy (also known as embolization) involves a catheter that is inserted into a large artery and then sealed off to prevent blood from flowing into the aneurysm. A Gamma Knife is a sophisticated radiosurgery machine that uses slim beams of radiation to precisely focus on a targeted area within the brain. The beams are so small, they do not damage the surrounding tissue, deliver a high dose of radiation to the area where the beams converge.
