Stereotactic radiotherapy or radiosurgery corporeal (SBRT) is used for the application of high doses of radiation to tumors of the liver, lungs, and spine. The procedure can be conducted in a single dose, or over the course of 2 to 5 sessions.
Stereotactic radiation therapy (SRT) is used to treat patients with primary benign, malignant brain tumors and metastatic brain cancer. It can also be used to treat specific inoperable brain tumors, and patients who have already been treated. SRT delivers a dose of radiation with extreme precision, while maintaining the surrounding healthy tissue, and minimizing the negative effects on the brain. Unlike radiosurgery, SRT takes between one and six weeks, depending on the complexity of the case.
Stereotactic radiosurgery (SRS) used in patients with primary and metastatic cancers of the brain, and inoperable brain tumors. SRS makes such a dramatic effect in the treatment area, that the changes are considered “surgical.” SRS is used for the irradiation of areas inaccessible to surgery and irregularly shaped tumors. SRS uses a higher dose of radiation that is precisely targeted to the tumor, while minimizing the possibility of damage to surrounding healthy tissues, such as the brain stem, nerves, eyes, and other critical structures. The duration of the procedure takes only one day, and is treated as an outpatient procedure.
Gamma Knife is one of the devices used in stereotactic radiosurgery for treatment of the following diseases: brain cancer; benign brain tumor; brain metastases; trigeminal nerve; swelling of the pineal gland; pituitary adenoma; speaker neuralgia; arteriovenous malformation (AVM); and thalamic pain syndrome.
With surgical precision, small beams of gamma-ray radiation are delivered to the affected area. This treatment is safe, accurate, and efficient, allowing you to avoid the risks and complications associated with traditional surgery. The procedure is performed in one day, and usually does not require hospitalization.
In addition to the gamma knife, radiosurgery may involve the use of Novalis, Cyber Knife, and the X- knife, as well as other similar treatments.
