    Summary

    Nuclear magnetic resonance (NMR) imaging enhances stereotactic surgery by providing precise brain visualizations. This method allows surgeons to directly locate targets in the operating room with superior grey and white matter contrast.

    Area of Science:

    • Neurosurgery
    • Medical Imaging
    • Radiology

    Background:

    • Stereotactic surgery requires precise localization of deep brain structures.
    • Traditional methods may have limitations in soft tissue contrast and multiplanar visualization.
    • Nuclear Magnetic Resonance (NMR) imaging offers unique physical properties for anatomical detail.

    Purpose of the Study:

    • To describe the application of NMR imaging within a stereotactic framework.
    • To highlight the advantages of NMR imaging for stereotactic neurosurgery.
    • To demonstrate the feasibility of intraoperative stereotactic localization using NMR.

    Main Methods:

    • Integration of NMR imaging with a stereotactic system.
    • Acquisition of brain scans in multiple planes (transaxial, coronal, sagittal) and arbitrary angles.
    • Direct visualization and localization of target structures by the surgeon.

    Main Results:

    • NMR imaging provides excellent contrast between grey and white matter.
    • The technique allows for precise visualization of target structures in three dimensions.
    • Stereotactic localization using NMR was achieved with satisfactory precision.

    Conclusions:

    • NMR imaging is a valuable tool for stereotactic neurosurgery.
    • Its multiplanar imaging capabilities and superior contrast enhance surgical precision.
    • Intraoperative NMR-guided stereotactic localization is a feasible and effective technique.
