A Gamma kinfe is a radiosurgical treatment that delivers a dose of gamma radiation to the target with surgical precision.
The Gamma Knife and its associated computerized treatment planning software enable physicians to locate and irradiate relatively small targets in the head (mostly inside the brain) with extremely high precision. Intense doses of radiation can be given to the targeted area(s) while largely sparing the surrounding tissues. The Gamma Knife can be used for a wide variety of problems. For example, it can be used to treat selected malignant tumors that arise in or spread to the brain (primary brain tumors or metastatic tumors), benign brain tumors (meningiomas, pituitary adenomas, acoustic neuromas), blood vessel defects (arteriovenous malformations) and functional problems (trigeminal neuralgia). Possible future uses are being evaluated for epilepsy and Parkinson's disease.
The Gamma Knife is usually unsuitable for targets larger than three or four centimeters in size.
The gamma knife can treat trigeminal neuralgia. It was qreat for me! I still suffer, but not like before. I had two other brain surgeries, and the gamma knife was best. See my hub on the condition.
