Summary
This study presents a stereotaxic CT method for precise neurosurgical targeting. The technique achieves sub-millimeter accuracy for brain tumor biopsies, enhancing patient safety and treatment outcomes.
Area of Science:
- Neurosurgery
- Medical Imaging
- Radiology
Background:
- Stereotaxic surgery requires precise localization of intracranial targets.
- Traditional stereotactic methods may have limitations in accuracy and radiation exposure.
- Advancements in computed tomography (CT) offer potential for improved stereotactic planning.
Purpose of the Study:
- To describe a novel stereotaxic CT method for neurosurgical applications.
- To evaluate the accuracy and reliability of this CT-guided stereotactic technique.
- To assess the clinical utility of the method for deep-seated brain tumors.
Main Methods:
- Development of a stereotaxic CT method at the Scientific Research Institute of Neurosurgery, AMS USSR.
- Integration with the Riechert-Mundinger stereotaxic apparatus.
- Utilizing a high-resolution (ND-8000) CT scanner and dedicated computer tomograph service programs for target calculation.
Main Results:
- The stereotaxic CT method enables target attainment with a mean error of no more than 1 mm in all directions.
- The method demonstrated simplicity and reliability in clinical application.
- Patient radiation exposure was relatively small.
Conclusions:
- The described stereotaxic CT method provides high accuracy for neurosurgical targeting.
- The technique is suitable for stereotactic biopsy of deeply located brain tumors.
- Recommended for neurosurgical clinics, particularly for brain tumor diagnosis and treatment.
