Gamma knife radiosurgery for prolactinomas

Journal of Neurosurgery, 2000
Object. In this retrospective investigation the authors examined the results of gamma knife radiosurgery (GKS) for tumor remnants after unsuccessful open surgery and medical treatment in 20 patients with prolactinomas. Particular attention is paid to a possible radioprotective action of dopamine agonists similar to the action of octreotide in ...

Gamma knife surgery for hemangioblastomas

Journal of Neurosurgery, 2005
Object. The authors reviewed their 14-year experience using stereotactic radiosurgery for the treatment of hemangioblastomas and define the role and the proper strategy for radiosurgery of this condition. Methods. This is a retrospective study of 38 hemangioblastomas in 13 patients. Seven patients had von Hippel—Lindau disease.

Dynamic gamma knife radiosurgery

Physics in Medicine & Biology, 2009
Gamma knife has been the treatment of choice for various brain tumors and functional disorders. Current gamma knife radiosurgery is planned in a ‘ball-packing’ approach and delivered in a ‘step-and-shoot’ manner, i.e. it aims to ‘pack’ the different sized spherical high-dose volumes (called ‘shots’) into a tumor volume.

Gamma Knife Radiosurgery for Meningioma

2019
Since its first reported use in 1976 in Sweden, Gamma Knife (GK) radiosurgery has become an accepted treatment option for intracranial meningioma, either upfront, in combination with planned subtotal resection, or as adjuvant/salvage treatment. Initially, GK was used in patients unfit for a major surgical procedure or for high-risk meningiomas adjacent

Gamma Knife evolving instrumentation

2022
There have been advances in both the hardware and software used in GKNS. The first major change in hardware had been Gamma Knife PERFEXION which introduced in 2006 had given more space for treatment, and removed the need for helmets, facilitating the treatment of complex conditions. Gamma Knife ICON was commissioned first in 2017.

Comparative clinical dosimetry with X-knife and gamma knife

Physica Medica, 2012
X-knife and gamma knife techniques are well-established for cranial stereotactic radiosurgery (SRS). Due to differences in their radiation delivery methods, some of the dosimetric parameters of these two techniques differ which may have clinical significance.

Gan to kagaku ryoho. Cancer & chemotherapy, 1993
The term "radiosurgery" was defined by Lars Leksell, a Swedish neurosurgeon, as the closed-skull destruction of a precisely defined intracranial target using high-dose radiation with stereotactic technique in a single session. For this purpose, the Gamma Knife was developed in 1968.

Physics and Dosimetry of the Gamma Knife

Neurosurgery Clinics of North America, 1992
Since 1968, the gamma knife has been one of the major radiosurgical devices. Although approximately 4300 patients worldwide had been treated with the gamma knife units through June 1990, gamma knife installments in the United States are still rather scarce compared to linear accelerators adapted for radiosurgery.
