Recovery
1-3 days; biological effect over weeks to months
Savings
~82% vs US
Average savings compared to US prices
Stereotactic radiosurgery using Gamma Knife technology to treat brain tumors, AVMs, trigeminal neuralgia, and functional disorders without open surgery. China has one of the largest installed bases of Gamma Knife units globally, with centers in major cities performing thousands of procedures annually. The non-invasive nature makes it suitable for patients who cannot undergo open craniotomy.
Treatment Planning Imaging
Stereotactic frame application followed by high-resolution MRI and/or CT angiography to precisely define the target volume and critical surrounding structures.
Duration: 2-3 hoursDose Planning
Neurosurgeon and radiation physicist collaboratively design the treatment plan, optimizing dose distribution to the target while minimizing radiation to normal brain tissue.
Duration: 1-3 hoursGamma Knife Irradiation
The patient is positioned in the Gamma Knife unit and receives the planned radiation dose in a single session. Multiple shots may be used to conform the dose to irregular targets.
Duration: 30 minutes - 3 hoursFrame Removal & Follow-up
Stereotactic frame is removed, brief observation period, and discharge with follow-up MRI schedule to monitor treatment response over the coming months.
Duration: Same day or overnight- Non-invasive — no incision, no general anesthesia needed
- Single-session treatment completed in one day
- Excellent tumor control rates for appropriate lesions
- Significant cost savings compared to Western radiosurgery
- Radiation effects develop slowly — weeks to months for full benefit
- Surrounding brain edema may occur requiring steroids
- Not suitable for large tumors (generally <3cm)
- Rare risk of radiation necrosis in adjacent tissue
