Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Radiation Oncology

Background:

  • A noninvasive adapter for CT-, MRI-, and angiography-guided stereotaxis was developed for morphological surgery.
  • Its accuracy led to applications in functional stereotaxis and external stereotactic irradiation.

Purpose of the Study:

  • To evaluate the utility of a noninvasive stereotactic adapter in various neurosurgical applications.
  • To highlight its adaptability for both diagnostic and therapeutic interventions.

Main Methods:

  • Utilized a noninvasive adapter with CT, MRI, and angiography for stereotactic guidance.
  • Applied the adapter for tumor biopsies, functional stereotaxis (thalamotomy, cingulotomy, hypothalamotomy, dentatotomy), and external stereotactic irradiation.
  • Employed the adapter for locating subcortical tumors and for percutaneous procedures with a phantom base.

Main Results:

  • The adapter demonstrated high accuracy in morphological and functional stereotaxis.
  • Successfully used for external stereotactic irradiation of brain tumors and arteriovenous malformations.
  • Enabled percutaneous tumor biopsy and ventriculostomy without a stereotactic frame.

Conclusions:

  • The noninvasive stereotactic adapter is a versatile and accurate tool for a range of neurosurgical procedures.
  • Its applications span from biopsies and functional neurosurgery to radiation therapy and minimally invasive interventions.
