The precise targeting of Gamma Knife radiation in a single, large dose makes it as effective as conventional surgery for certain brain conditions but Gamma Knife radiosurgery is a method to non-invasively boost the effectiveness of radiation delivered to the tumor. It is a type of stereotactic radiosurgery (SRS) and similar to other techniques such as CyberKnife and X-Knife. In fact, Gamma Knife is the only non-invasive radiosurgery system specifically engineered to treat delicate brain tissue. It is associated with a low risk of facial paresthesias, an approximate 80% rate of significant pain relief, and a low recurrence rate in patients who initially attain complete relief. Lunsford LD, Niranjan A, Kano H, et al.

After a brain tumor has been diagnosed on imaging, a biopsy will sometimes be taken to determine if the cells are cancerous or benign. The Gamma Knife is not a knife in the conventional sense, but uses a focused array of intersecting beams of gamma radiation to treat lesions within the brain. Because of the anatomic distortions that are inherent to MR units, the target should be placed as near to the center of the frame as possible. Because these treatments work by damaging the trigeminal nerve, the rate of sensory side effects such as numbness and painful dysesthesias is higher than in microvascular decompression.

IGRT, image-guided radiation Gamma Knife is actually the name of the technique and the equipment that is used to deliver precise radiation to the tumor site. Neurosurgery or neurological surgery, known in common parlance as brain surgery, is the medical specialty concerned with the prevention, diagnosis, surgical treatment, and rehabilitation of disorders which affect any portion of the nervous system including the brain, spinal cord, central and peripheral nervous system, and cerebrovascular system. Prior to the procedure, a stereotactic frame is attached to the head, and an MRI / CT is performed of the brain to determine the size and location of the tumor Complete Back and Spine Care. Deus Cielo, MD received his medical degree from the Brown-Dartmouth Medical Program of Dartmouth Medical School and Brown Medical School. Radiosurgery delivers multiple beams of radiation to the pituitary adenoma with stereotactic precision using a frame affixed to the head, usually in a single session and at most in 5 sessions.

Newer forms of radiosurgery include Micro-MLC radiosurgery, fractionated radiosurgery (also referred to as Stereotactic Radiotherapy and vice versa) and NeuroTomotherapy. Its precision in delivering a single, high dose of radiation to a tumor makes Gamma Knife radiosurgery an excellent, non-invasive treatment option for a variety of brain tumors. Radiosurgery was originally defined as a single-fraction technique that used stereotactic principles for targeting and treatment of intracranial lesions through the use of multiple noncoplanar beams (SRS). It is used to shrink tumors and treat tangled blood vessels. Therapeutic X-ray or ionizing radiation is in the energy range of 105 eV and higher.

No precise data are available on the risk of endocrine side effects of this treatment. Instead the procedure, also known as stereotactic radiosurgery, uses high-energy gamma rays to pinpoint and destroy tumors or other brain abnormalities. The benefit of WBRT has not changed markedly despite alterations in dose, fractionation schedules, or the addition of radiosensitizers. … During treatment, the patient with the stereotactic frame is locked to the treatment couch, and the plan parameters with respect to the frame are transferred to the Gamma Knife treatment unit so that the beams can be precisely delivered to the target. The beams of radiation are very precisely focused to reach the tumor, lesion, or other area being treated with minimal effect on surrounding healthy tissue. American Institute of Physics, Woodbury, NY; 1995. Our team of world-renowned neurosurgeons uses the most advanced surgical techniques to treat brain diseases and disorders.
