    CT-guided stereotactic biopsies are safe and accurate for obtaining intracranial tissue. Two methods using modified or standard stereotactic frames with CT guidance were evaluated in 15 patients.

    Area of Science:

    • Neurosurgery
    • Medical Imaging
    • Neurology

    Background:

    • Stereotactic biopsy is crucial for diagnosing intracranial lesions.
    • Accurate targeting of lesions is essential for diagnostic yield and patient safety.
    • Advancements in imaging technology, like computed tomography (CT), offer potential for improved stereotactic procedures.

    Purpose of the Study:

    • To evaluate the safety and accuracy of CT-guided stereotactic biopsy techniques for intracranial tissue acquisition.
    • To compare two distinct methods of CT-guided stereotactic biopsy.
    • To assess the feasibility of obtaining intracranial tissue samples using stereotactic systems integrated with CT imaging.

    Main Methods:

    • Retrospective analysis of 15 patients undergoing intracranial CT-guided stereotactic biopsies.

  • Utilized two stereotactic systems: a modified Riechert-Mundinger frame for CT use and a standard frame with CT-based landmark localization.
  • Biopsies were performed to obtain tissue from intracranial lesions under CT guidance.

    • Main Results:

    • Both CT-guided stereotactic biopsy methods demonstrated safety in obtaining intracranial tissue.
    • The accuracy of tissue acquisition was confirmed for both employed stereotactic systems.
    • No significant complications were reported related to the biopsy procedures in the evaluated cohort.

    Conclusions:

    • CT-guided stereotactic biopsy is a safe and accurate method for intracranial tissue diagnosis.
    • Both modified and standard stereotactic frames, when integrated with CT guidance, provide reliable approaches.
    • These techniques facilitate precise tissue sampling, aiding in the diagnosis of neurological conditions.
