Area of Science:

  • Neurosurgery
  • Radiology
  • Medical Imaging

Background:

  • Stereotactic neurosurgery requires precise localization for diagnostic procedures.
  • Conventional cerebral angiography can be complex to integrate with stereotactic frameworks.
  • Standard operating room equipment often lacks specialized angiography components.

Purpose of the Study:

  • To describe a simple, integrated system for cerebral angiography under stereotactic conditions.
  • To demonstrate the utility of standard components for advanced neuroimaging.
  • To highlight the benefits of a unified coordinate system for brain tumor diagnosis.

Main Methods:

  • Integration of a film changer and injection pump into a stereotactic arrangement.
  • Utilizing standard X-ray tubes and power generators.

    • Main Results:

    • Successful acquisition of cerebral angiographic documents with reduced magnification.
    • Demonstration of sufficient topographical orientation with 5 films per seriogram.
    • Capability for stereoscopic viewing through precise head rotation.
    • Integration of CT scan, angiography, and ventriculography within a single reference system.

    Conclusions:

    • The described system offers a simplified approach to stereotactic cerebral angiography.
    • Reduced X-ray magnification and stereoscopic viewing enhance diagnostic information.
    • Combining multiple diagnostic procedures in a unified coordinate system provides significant advantages for brain tumor patients.
