    Summary

    Intraoperative computed tomographic (CT) scanning enabled precise brain tumor removal in three patients. This advanced imaging technique improves tumor localization and visualization, potentially making previously unresectable tumors treatable.

    Area of Science:

    • Neurosurgery
    • Medical Imaging
    • Oncology

    Background:

    • Glial brain tumors pose significant surgical challenges.
    • Accurate intraoperative localization and visualization are critical for successful tumor resection.
    • Existing imaging modalities may have limitations during complex surgical procedures.

    Purpose of the Study:

    • To evaluate the utility of a dedicated intraoperative computed tomographic (CT) scanner for precise resection of glial brain tumors.
    • To assess the impact of intraoperative CT imaging on tumor localization and visualization.
    • To explore the potential of intraoperative CT guidance for previously unresectable tumors.

    Main Methods:

    • A therapeutic computed tomographic (CT) scanner designed for surgical use was employed.

  • Intraoperative CT imaging was performed during precise resections in three patients with glial brain tumors.
  • Image analysis focused on tumor localization, contrast, spatial resolution, and anatomical depiction.

    • Main Results:

    • The intraoperative CT scanner provided accurate tumor localization.
    • Superior contrast and spatial resolution of the brain lesions were achieved.
    • Detailed cross-sectional anatomy of the entire brain was visualized during surgery.

    Conclusions:

    • Intraoperative CT imaging is a valuable tool for precise glial brain tumor resection.
    • This technology enhances surgical decision-making by improving tumor visualization.
    • Further development of intraoperative CT guidance may enable safer and more complete removal of challenging brain tumors, including those previously considered unresectable.
