What should you know about gamma knife esprit?

The name refers to a Gamma Knife treatment platform, not a surgical blade. Imaging helps the team map the target and protect nearby brain tissue as much as possible. It may be considered for certain brain metastases, benign or malignant brain tumours, and other carefully selected intracranial problems. Suitability depends on the target's size, position, number, symptoms, previous treatment and overall health.

Treatment planning can involve a head frame or a frameless mask, depending on the centre and clinical plan. Radiation is delivered while you remain still; the treatment does not remove a tumour immediately. Changes are checked over time with clinical review and brain imaging.

Bring your scan reports, medication list and information about implanted devices. Ask whether you should take usual medicines, including medicines for seizures or swelling, on the treatment day. Arrange transport if sedation is planned, and follow instructions about eating, drinking and hair or skin preparation. Discuss pregnancy, blood-thinning medicines and any difficulty lying flat before planning begins.

Your team should explain the target, expected schedule, alternatives and follow-up scans. Related information is available under [Gamma Knife](/technology/gamma-knife/) and [Stereotactic Radiosurgery](/treatments/radiation-oncology/stereotactic-radiosurgery/).

Contact the treating team promptly for worsening headache, repeated vomiting, new weakness, confusion, a seizure, new vision or speech changes, fever, or increasing redness or discharge where a frame or access device touched the skin. Sudden severe symptoms, collapse or a first seizure need emergency care.

Which target is being treated, and what imaging defines it? Will treatment use a frame or mask? What symptoms should prompt an urgent call? When will follow-up imaging assess the response?
