Gamma Knife Radiosurgery
Gamma Knife Radiosurgery is an advanced, non-invasive treatment method designed for precise management of brain tumors and selected neurological conditions. Despite its name, it does not involve any surgical incision. Instead, it delivers highly focused radiation beams to the target area while minimizing exposure to surrounding healthy tissue.
At Sante Oncology Centers, this technology allows effective treatment in a single session, offering patients a safe and comfortable alternative to traditional brain surgery.
What is Gamma Knife Radiosurgery?
Gamma Knife is a specialized form of stereotactic radiosurgery used to treat abnormalities within the brain. It delivers a single, high dose of radiation with sub-millimeter accuracy, targeting tumors and other conditions without affecting surrounding healthy tissue.
It is particularly effective for small to medium-sized lesions and is widely used in modern neuro-oncology.
How the Treatment Works
The precision of Gamma Knife treatment is achieved through advanced imaging techniques such as CT and MRI, combined with computer-assisted planning systems. These technologies create a detailed three-dimensional map of the brain, allowing physicians to accurately identify and target the treatment area.
Multiple radiation beams are directed simultaneously at the target, delivering a high dose to the lesion while protecting surrounding healthy tissue.
Conditions Treated
- Brain tumors
- Brain metastases
- Arteriovenous malformations (AVMs)
- Trigeminal neuralgia
- Acoustic neuroma
- Pituitary tumors
- Meningiomas
- Gliomas
- Epilepsy (selected cases)
- Essential tremor
Treatment Procedure
The procedure begins with the application of a stereotactic frame to ensure precise targeting. Advanced imaging is then performed to identify the exact location of the condition.
During the treatment, the patient lies comfortably while the system delivers multiple focused radiation beams to the target area. The procedure is painless and does not require general anesthesia.
Treatment duration varies depending on the diagnosis, but most sessions are completed within a few hours.
Recovery and Aftercare
Gamma Knife treatment is typically performed on an outpatient basis, allowing patients to return home the same day. Most individuals resume normal activities within a short time.
Some patients may experience mild side effects such as headache or fatigue, which can be managed with medication. Follow-up appointments are scheduled to monitor treatment outcomes.
What is Gamma Knife treatment?
Gamma Knife is a non-invasive radiosurgery technique used to treat brain tumors and certain neurological conditions with high precision.
Is Gamma Knife a surgical procedure?
No, it does not involve any incision or surgery. It uses focused radiation beams to treat the target area.
How long does Gamma Knife treatment take?
The procedure is usually completed within a few hours and is typically done in a single session.
What conditions can be treated with Gamma Knife?
It is used for brain tumors, metastases, arteriovenous malformations (AVMs), trigeminal neuralgia, and other neurological conditions.
Do patients need hospitalization?
No, most patients can return home the same day after treatment.
Is the treatment painful?
No, the procedure is painless. Some patients may experience mild discomfort due to positioning.
