radiosurgia

Radiosurgery is a non-invasive medical technique that delivers highly focused radiation to treat specific areas of the body with precision. Unlike traditional radiation therapy, which targets larger volumes of tissue, radiosurgery concentrates radiation on small, well-defined lesions, such as tumors or abnormal blood vessels, while sparing surrounding healthy tissue. This approach minimizes damage to nearby structures, reducing side effects and enabling faster recovery.

The most common form of radiosurgery is stereotactic radiosurgery (SRS), often performed using specialized equipment like the Gamma Knife or linear accelerators. These systems use advanced imaging, such as MRI or CT scans, to map the target area in three dimensions, allowing for precise treatment planning. The radiation is then delivered in a single session or over a few sessions, depending on the clinical indication.

Radiosurgery is primarily used to treat brain tumors, arteriovenous malformations (AVMs), trigeminal neuralgia, and metastatic brain lesions. It can also be applied to non-brain targets, such as spinal tumors or liver metastases, through techniques like stereotactic body radiation therapy (SBRT). The procedure is typically performed on an outpatient basis, with patients returning home the same day.

One of the key advantages of radiosurgery is its ability to provide effective treatment with minimal disruption to daily life. However, it is not suitable for all patients, and its use depends on factors such as tumor size, location, and overall health. Side effects are generally mild and temporary, though rare complications, such as swelling or radiation-induced damage, may occur. Radiosurgery is often considered alongside other treatments, including surgery, chemotherapy, and conventional radiation therapy, as part of a comprehensive care plan.
