Which procedure uses an intracranial guiding device to deliver high-dose radiation the precisely targeted tumor tissue?

The procedure that uses an intracranial guiding device to deliver high-dose radiation precisely targeted tumor tissue is called Stereotactic Radiosurgery (SRS). SRS is also referred to as stereotactic ablative radiotherapy (SABR).

SRS is a highly advanced form of radiotherapy that involves delivering a precisely focused beam of high-energy radiation to a small, well-defined target, such as a tumor, while minimizing damage to surrounding healthy tissue. It is commonly used to treat small, inoperable, or surgically complex tumors to eradicate them or provide additional control post-operatively.

To achieve the utmost precision, SRS is often directed using stereotactic image guidance systems combined with sophisticated treatment planning and computational technology. It enables the precise delivery of higher tumoricidal doses of radiation in fewer sessions compared to traditional radiotherapy, thus minimizing the number of treatments the patient needs to undergo.

SRS is used as a non-invasive treatment option for tumors in various brain locations, including those found in the skull base, deep-seated brain regions, near critical structures (such as the brainstem or optic nerves), and even spinal tumors. Due to its accuracy and the minimal invasiveness, the SRS procedure allows many patients to be treated as outpatients or with a significantly shortened hospital stay, enhancing the overall patient experience and preserving their quality of life.
