This in turn implies more normal tissue exposed to high doses, which could result in negative treatment side effects. As a consequence, stereotactic body radiotherapy is mostly delivered in a limited number of fractions, thereby blending the concept of stereotactic radiosurgery with the therapeutic benefits of fractionated radiotherapy.

Stereotactic External-Beam radiation Therapy, sometimes called SBRT is now being used to treat Small Cell Lung Cancer, and Sarcomas that have metastasized to the lungs. The high doses used in thoracic SBRT can sometimes cause adverse effects ranging from mild rib fatigue and transient esophagitis , to fatal events such as pneumonitis or hemorrhage.
Radiosurgery is surgery using radiation, [1] that is, the destruction of precisely selected areas of tissue using ionizing radiation rather than excision with a blade. Like other forms of radiation therapy (also called radiotherapy), it is usually used to treat cancer.
Stereotactic radiosurgery (SRS) is when doctors use a single or several stereotactic radiation treatments of the brain or spine. Stereotactic body radiation therapy (SBRT) refers to one or several stereotactic radiation treatments with the body, such as the lungs.
Stereotaxis may refer to: . Any of various stereotactic techniques or procedures: . Stereotactic surgery, any of various minimally invasive surgery types that make use of a three-dimensional coordinate system to locate small targets for ablation, biopsy, injection, stimulation, implantation, or radiosurgery
Surgical resection followed by stereotactic radiosurgery or whole-brain irradiation deliver superior survival compared to whole brain irradiation alone. [6] Therefore, in patients with only one metastatic brain lesion and controlled or limited systemic disease, a life expectancy of at least 3 months with maintenance of performance status might ...

in stereotactic radiosurgery, a headframe is applied to a patient. [7] MRI or CT scans are then administered on the patient to allow a map of the head/brain to be formed. This map will then be used as a guide to allow correct orientation of the lasers administering radiation to specifically destroy the pituitary gland or part of the pituitary gland.
