|The physicians of Florida
Oncology Network are pleased to be a part of a multidisciplinary team providing care at
the Gamma Knife Center at Florida Hospital.
The Gamma Knife uses non-invasive gamma rays to treat deep-seated brain lesions that were once thought to be inoperable. This out patient procedure uses precisely directed beams of radiation to destroy diseased tissue or tumors of the brain which are determined to be unsuitable for open surgery.
The Gamma Knife has been shown effective in treating certain functional disorders such as trigeminal neuralgia, certain psychiatric disorders and intractable pain as well as effective treatment of small to mid-sized brain tumors and vascular malformations.
The treatment day normally lasts from two to six hours, with the bulk of the day spent on treatment planning and preparation. The medical team consisting of radiation oncologists, neurosurgeons, neuroradiologists, radiation physicists and nurses, works together to provide patient care. Preparation includes placement of the stereotactic headframe on the patient which helps to stabilize the patients head during treatment and helps to identify the target prior to treatment. Magnetic resonance imaging (MRI) , computerized tomography (CT) and/or angiography is used to locate the area needing treatment. While the patient waits in a comfortable holding area with their family, the complex planning phase is completed. Gamma Knife radiosurgery is generally the shortest phase of the day and is virtually painless. Patients generally resume normal daily activities within one to three days after surgery.
