Cervical disk herniation: CT demonstration after contrast enhancement.

E J Russell, C M D'Angelo, R D Zimmerman

    Radiology
    |September 1, 1984

    Summary

    Contrast-enhanced CT scans improve visualization of cervical radiculopathy causes. This technique offers better anatomic detail than non-contrast scans, aiding diagnosis and potentially replacing myelography.

    Area of Science:

    • Radiology
    • Neurosurgery
    • Diagnostic Imaging

    Background:

    • Cervical radiculopathy diagnosis often relies on imaging.
    • Computed Tomography (CT) is a common diagnostic tool.
    • Enhancing CT with contrast medium may improve diagnostic accuracy.

    Observation:

    • Transverse axial CT scans were performed on 25 patients with cervical radiculopathy.
    • Scans were acquired before and after intravenous contrast administration.
    • Ventral epidural and intervertebral foraminal veins were visualized.

    Findings:

    • Contrast enhancement improved visualization of venous structures and dura mater.
    • Post-infusion CT demonstrated posterior displacement of enhanced epidural veins.
    • Enhanced epidural veins and enhancement around disk fragments clearly delineated disk extrusion.

    Implications:

    • Infusion CT provides superior anatomic definition compared to non-contrast CT.
    • This technique can increase diagnostic certainty for cervical radiculopathy.
    • Enhanced CT may obviate the need for myelography in select cases.
