    Computer-assisted myelography (CAM) enhances spinal cord imaging by combining computed tomography (CT) with metrizamide. CAM offers superior detail for spinal lesions compared to conventional methods, proving useful as a primary or complementary diagnostic tool.

    Area of Science:

    • Radiology
    • Neurology
    • Medical Imaging

    Background:

    • Computer-assisted myelography (CAM) integrates computed tomography (CT) with intrathecal metrizamide for spinal cord visualization.
    • Routine metrizamide myelography is a standard diagnostic procedure for spinal pathologies.

    Purpose of the Study:

    • To evaluate the diagnostic utility of Computer-assisted myelography (CAM) compared to conventional myelography.
    • To identify clinical indications for CAM as a primary or adjunctive diagnostic study for spinal cord lesions.

    Main Methods:

    • Retrospective review of 139 Computer-assisted myelography (CAM) procedures performed at Emory University Hospital.
    • Analysis included 125 secondary CAMs (following routine myelography) and 14 primary CAMs.
    • Comparison of CAM findings with conventional myelography and other radiodiagnostic studies.

    Main Results:

    • Eighty-one CAMs (58%) identified pathological processes.
    • In secondary CAMs with pathology, 67% revealed details not seen on routine myelography.
    • CAM demonstrated superiority in visualizing cervicomedullary, extradural, intradural, extramedullary, and intramedullary lesions.

    Conclusions:

    • Computer-assisted myelography (CAM) is a valuable tool for diagnosing spinal cord and spine pathologies, often providing superior detail.
    • CAM is indicated for complex cases requiring enhanced visualization and can be used as a primary or complementary study.
    • CAM should be used judiciously, complementing rather than entirely replacing conventional CT and myelography.
