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 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 surgery for neurocytoma

Journal of Neurosurgery, 2007
Object Although considered benign tumors, neurocytomas have various biological behaviors, histological patterns, and clinical courses. In the last 15 years, fractionated radiotherapy and radiosurgery in addition to microsurgery have been used in their management.

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.

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.

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.

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.

A Comparison of Craniotomy and Gamma Knife Charges in a Community-Based Gamma Knife Center

Stereotactic and Functional Neurosurgery, 1997
The hospital charges for all craniotomies and transsphenoidal procedures were gathered for a 4-year period from a single, non-profit hospital serving San Diego, Calif., USA. Of the individuals in this community, 65% are covered by a variety of managed health care programs which have greatly discounted hospital receipts on a per diem or capitated ...
