The difference between r-knife and whole brain radiotherapy

1, the principle of treatment: r knife is a non-invasive radiation therapy technology, using multiple directed radiation beams focused on the brain lesions, high-dose radiation to accurately destroy the lesion tissues, while completely protecting the surrounding healthy tissues. Whole brain radiotherapy, on the other hand, uses low doses of radiation to treat the entire brain by extensively irradiating the entire brain.

2. Indications: r-knife is mainly used to treat benign or malignant tumors, aneurysms, and cranial nerve disorders within the skull. Whole brain radiotherapy is usually used to treat multiple metastatic tumors, intracranial metastatic tumors and other disease conditions that require whole brain coverage.

3. Therapeutic effect: r-knife has high precision and high efficacy, which can deliver the radiation dose to the lesion while protecting normal brain tissues, providing better therapeutic effect. Whole brain radiotherapy covers the whole brain and can treat multiple lesions at the same time, but the dose is smaller and the efficacy is relatively low.
