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.
