    Metrizamide enables consistent and prompt whole-spinal cord myelography, including the foramen magnum region. This contrast agent is convenient and effective for spinal imaging, despite some potential side effects.

    Area of Science:

    • Radiology
    • Neurology
    • Medical Imaging

    Background:

    • Myelography is crucial for visualizing the spinal cord.
    • Evaluating the entire spinal cord, including the cervical and foramen magnum regions, presents technical challenges.

    Purpose of the Study:

    • To assess the efficacy and safety of metrizamide for comprehensive spinal myelography.
    • To determine if metrizamide facilitates prompt and consistent imaging of the entire spinal cord.

    Main Methods:

    • Metrizamide was administered via lumbar or lateral cervical puncture for whole-spinal cord myelography.
    • Specific patient positioning and table tilt were employed to ensure contrast filling of the cervical region.
    • Multiple projections were used for filming each spinal region.

    Main Results:

    • Consistent and prompt visualization of the entire spinal cord, including the foramen magnum, was achieved.
    • Adequate imaging of the cervical and foramen magnum regions was obtained in all cases.
    • Contrast material dilution was noted in a small percentage of thoracic region studies.
    • Mild to moderate side effects occurred in 49 patients; no seizures were reported.

    Conclusions:

    • Metrizamide is a convenient, efficient, and acceptable contrast medium for complete spinal cord myelography.
    • The described technique allows for thorough examination of the entire spinal axis.
    • Metrizamide facilitates comprehensive spinal imaging when indicated.
