Stereotactic radiosurgery (SRS) and stereotactic body radiation therapy (SBRT) are both highly precise types of radiation therapy that use advanced imaging techniques and computer software to deliver a high dose of radiation to a small, well-defined target.
SRS is typically used to treat small, well-defined tumors or abnormalities within the brain or other parts of the body. It delivers a high dose of radiation to the target in a session, which can be completed in as little as 30 minutes. SRS is often used for conditions such as brain tumors, trigeminal neuralgia, and arteriovenous malformations (AVMs).
SBRT is typically used to treat larger tumors or abnormalities within the body, such as those found in the lung, liver, or prostate. SBRT delivers a high dose of radiation to the target over several sessions, usually 1-5, with each session lasting a few minutes. SBRT is often used to treat cancer that has spread to other parts of the body or is difficult to reach with surgery.
