Stereotactic radiotherapy (SRT) and stereotactic radiosurgery (SRS) are advanced techniques in the field of radiation oncology used to treat various medical conditions, primarily tumors, with precision and minimal damage to surrounding healthy tissue. SRT is used to deliver precisely targeted radiation therapy to a tumor or lesion over multiple treatment sessions. It is typically used for larger tumors or lesions, and it aims to control or shrink the tumor over time. SRT can be used for both malignant and benign tumors. It is commonly used for brain tumors where precise radiation delivery is essential. Unlike SRT, SRS doesn’t involve fractionation; it delivers a highly concentrated dose of radiation in a single session. SRS is primarily used for small, well-defined brain tumors or tumors in other parts of the body where precise targeting is essential. It is also used for certain functional disorders like trigeminal neuralgia, non-malignant conditions like Arteriovenous malformations (AVMs).
