    Area of Science:

    • Neurosurgery
    • Medical Imaging
    • Surgical Technology

    Background:

    • Precise targeting is crucial for successful functional neurosurgery.
    • Conventional roentgenographic methods have been the standard for stereotactic procedures.
    • Advancements in imaging technology necessitate evaluation of new techniques.

    Purpose of the Study:

    • To investigate the accuracy of CT-guided stereotactic techniques.
    • To compare CT-guided targeting with conventional roentgenographic methods.
    • To assess the reliability of the Brown-Roberts-Wells (BRW) system in CT-guided stereotactic surgery.

    Main Methods:

    • Stereotactic surgery was performed using the Brown-Roberts-Wells (BRW) system.
    • Procedures included 9 functional neurosurgeries with roentgenography and 17 intracranial neoplasm biopsies with CT-guidance.

  • Accuracy of target points determined by CT-guided techniques was evaluated.

    • Main Results:

    • CT-guided stereotactic surgery with the BRW system showed no accuracy issues in determining target points.
    • For functional neurosurgery, CT-guided targeting exhibited a discrepancy of within 2 mm compared to conventional methods.
    • The study confirmed the accuracy of CT-guided stereotactic surgery for biopsies.

    Conclusions:

    • CT-guided stereotactic surgery with the BRW system is an accurate method for neurosurgical targeting.
    • The technique is reliable for both functional neurosurgery and intracranial biopsies.
    • CT-guidance provides a viable alternative to roentgenographic methods with comparable accuracy.
