    Computed tomographic myelography (CTM) is effective for identifying cervical nerve root avulsions, offering diagnostic accuracy comparable to traditional myelography. This imaging technique also reveals associated bony or soft tissue injuries.

    Area of Science:

    • Radiology
    • Neurology
    • Medical Imaging

    Background:

    • Cervical nerve root avulsion is a significant injury.
    • Accurate diagnosis is crucial for patient management.
    • Traditional myelography has limitations in visualizing certain details.

    Purpose of the Study:

    • To evaluate the effectiveness of computed tomographic myelography (CTM) in diagnosing cervical nerve root avulsions.
    • To describe the specific CTM appearance of these avulsions.
    • To compare CTM findings with traditional myelography.

    Main Methods:

    • CTM using metrizamide was performed on six patients.
    • Twelve cases of cervical nerve root avulsion were identified.
    • Findings were confirmed by cervical myelography and physical examination.

    Main Results:

    • CTM accurately depicted cervical nerve root avulsions.
    • Characteristic findings included ventrolateral outpouchings of contrast material into the neural foramen.
    • These CTM findings were distinct from normal variants like dilated nerve root sleeves.

    Conclusions:

    • CTM is a sensitive and accurate imaging modality for cervical nerve root avulsion.
    • CTM provides diagnostic performance equal to myelography.
    • CTM offers additional value by visualizing bony fragments and soft tissue injuries.
