Treat a broad range of intracranial indications

Our users treat >60 different indications* with Leksell Gamma Knife. Every treatment is personalized to fit the patients need and condition.

Explore a selection of case studies to find out more:

*Based on LGK Society Treatment Statistics 2020

Brain metastases

By six months post second treatment, the metastasis was no longer evident by MRI. Patient symptoms diminished and no recurrence was observed in one year of MRI control.

Trigeminal Neuralgia

Pain alleviation using conservative treatment was not sufficient for this multiple sclerosis patient. Gamma Knife radiosurgery provided an effective, non-invasive alternative to achieve excellent results, reducing facial pain significantly.

Read case study

Vestibular Schwannoma

Gamma Knife radiosurgery provided good control of tumor growth with no deterioration of symptoms. The excellent conformation of dose to the tumor that was achieved with Gamma Knife enabled preservation of the facial nerve.

Protect your patient's quality of life with very low dose to the brain and body

Brain

By delivering the radiation dose with 192 small beams to a focused isocenter, Gamma Knife radiosurgery has 2-4x lower dose to healthy brain tissue compared to competing technologies.

Body

The unique design of Leksell Gamma Knife means that there is less radiation outside the target and no primary beams are directed from the top of the head through the body, resulting in 2-235x lower dose to body compared to competing technologies.
