Yes. Once we have reviewed imaging and medical records, our specialists will discuss whether Gamma Knife is a suitable option and what the process will involve. We will address your key questions upfront, ensuring you have a clear plan before you travel.
We provide support in multiple languages, including English and Spanish. You do not need to speak Japanese to consult with us.
While we do not book flights or accommodations on your behalf, we can provide practical information on travel and local guidance. We are happy to point you toward helpful resources to assist with your arrangements.
We can guide you on the documents that may be required and provide supporting materials when available and appropriate. Requirements vary by country and individual circumstances, so we'll confirm details case by case.
Most patients complete their evaluation and treatment within a short stay of 2–3 days, though this varies by case. Gamma Knife is typically performed on an outpatient basis, meaning many patients can return to their accommodation on the same day as their procedure.
We generally recommend follow-up imaging once a year to monitor your progress. After you return home, we will provide a clear timeline and guide you on which images to obtain and when.
Note: Follow-up imaging will need to be arranged and performed by your local healthcare provider.
