Radiosurgery precisely targets in-brain lesions using focused radiation beams, offering a non-invasive alternative to traditional neurosurgery. Advances in imaging and technology continue to expand its applications for treating brain conditions.

Area of Science:

  • Neurosurgery
  • Radiation Oncology
  • Medical Physics

Background:

  • Radiosurgery is a minimally invasive technique for treating brain lesions.
  • It utilizes focused ionizing radiation beams to target lesions precisely.
  • This method avoids the complications associated with open-skull neurosurgery.

Purpose of the Study:

  • To provide an overview of radiosurgery as a treatment modality.
  • To highlight its historical development and technological advancements.
  • To discuss the different radiation sources employed in radiosurgery.

Main Methods:

  • Convergence of multiple thin ionizing beams at a focal point.
  • Utilizes Gamma Knife (cobalt-60), LINAC X-rays, or protons.
  • Submillimetric precision in radiation delivery.

Main Results:

  • Therapeutic effect achieved without craniotomy.
  • Reduced risk of complications compared to conventional neurosurgery.
  • Expanded indications due to advancements in imaging techniques.

Conclusions:

  • Radiosurgery is an established and evolving treatment for intracranial lesions.
  • Technological refinements continue to improve precision and efficacy.
  • It represents a significant advancement in neurosurgical and oncological treatment options.
