An overview of CT based stereotactic systems for the localization of intracranial lesions

Area of Science:

• Neurosurgery
• Medical Imaging
• Radiology

Background:

• Computed tomography (CT) offers high accuracy in identifying and localizing intracranial lesions.
• Stereotactic neurosurgery requires precise localization of targets within the brain.
• Integrating advanced imaging with surgical techniques is crucial for minimally invasive procedures.

Purpose of the Study:

• To provide an overview of existing systems that adapt computed tomography for stereotactic neurosurgical procedures.
• To review the literature on the integration of CT scanning with stereotactic frames.
• To highlight the technological adaptations enabling CT-guided stereotactic surgery.

Main Methods:

• Review of published literature describing CT-based stereotactic neurosurgical systems.
• Analysis of different approaches, including conventional CT scans and dedicated operating room scanners.
• Examination of various stereotactic frame adaptations and custom-designed frames.

Main Results:

• Multiple systems utilize CT data for stereotactic neurosurgery, ranging from conventional scans to dedicated OR scanners.
• The GE-8800 CT scanner is frequently employed, but other models are also suitable.
• Both adapted commercial and specifically designed stereotactic frames are in use.

Conclusions:

• Computed tomography integration significantly enhances the precision of stereotactic neurosurgery.
• The reviewed systems demonstrate the feasibility and variety of approaches for CT-guided stereotactic procedures.
• Further development and standardization of CT-based stereotactic systems can improve patient outcomes.
