Radiosurgery

Neurosurgery, 2007
Despite the abundant reports on clinical efficacy of radiosurgery (high-dose focused radiation) for the treatment of brain tumors, vascular malformations, and functional disease, limited histological information is available after treatment that might allow a better understanding of the response of the target and the surrounding brain to the delivered ...

Radiosurgery imaging

2022
The most important imaging technology for GKNS continues to be magnetic resonance. The introduction of 3 Tesla machines permits quicker studies with better signal to noise ratio. The more powerful magnet increases the chances of heating the points of contact between patient and frame, but this has been solved with non-conducting nuts. There are several

Repeat Radiosurgery Treatment After Cavernous Malformation Radiosurgery

World Neurosurgery, 2018
Of cavernous malformations (CMs) treated with radiosurgery (RS), 5% bleed after 2-year initial latency period. This rate is similar to failure rate of RS for other pathologies, which often require repeat RS for favorable outcome. The aim of this pilot study was to define failure of CM RS and to assess safety of second RS.Retrospective analysis was ...

Radiosurgery

Critical Reviews in Neurosurgery, 1999
This review looks at papers dealing with radiosurgery for tumors, cavernous malformations, and arteriovenous malformations. The tumors were meningiomas, many of them at the base of the brain, and the results were excellent. One paper used the gamma knife for patients with cavernous malformations.

[Radiosurgery].

Revue neurologique, 1997
Radiosurgery refers to the possibility of the destruction of a small area in the brain with a high dose of radiation, after determination of the target with stereotactic coordinates. Arteriovenous malformations of small size not treatable by direct surgery are obliterated by radiosurgery in nearly 80 p. 100 of the cases.

LINAC Radiosurgery

Neurosurgery Clinics of North America, 1990
During the past decade, multiple linear accelerator (LINAC) radiosurgical systems have been developed. By measuring beam energy, beam accuracy, and dose gradient, it is possible to compare them to the older radiosurgical device, the gamma knife. LINAC systems appear to be advantageous in terms of cost, variety of collimator sizes available, and ...

Evaluation of radiosurgery techniques–Cone-based linac radiosurgery vs tomotherapy-based radiosurgery

Medical Dosimetry, 2013
Performances of radiosurgery of intracranial lesions between cone-based Linac system and Tomotherapy-based system were compared in terms of dosimetry and time. Twelve patients with single intracranial lesion treated with cone-based Linac radiosurgery system from 2005 to 2009 were replanned for Tomotherapy-based radiosurgery treatment.
