Cervical radiculopathy: computed tomography and myelography compared.

D L Daniels, J P Grogan, J G Johansen

    Summary

    Computed tomography (CT) is more accurate than myelography for diagnosing cervical radiculopathy caused by disk herniation. CT imaging may reduce the need for myelography in evaluating cervical disk disease.

    Area of Science:

    • Radiology
    • Neurology
    • Neurosurgery

    Background:

    • Cervical disk herniation diagnosis lacks established CT accuracy metrics compared to lumbar cases.
    • Cervical radiculopathy is often caused by disk herniation or spondylosis.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy of CT scans versus myelography for cervical radiculopathy.
    • To compare CT with and without intrathecal metrizamide to myelography.

    Main Methods:

    • Blind, independent evaluation of cervical myelograms and CT scans.
    • Patients had confirmed cervical radiculopathy via clinical examination, surgery, and EMG.
    • Statistical analysis and receiver operating characteristic (ROC) curves were employed.

    Main Results:

    Related Experiment Videos

    • CT scans, with or without intrathecal metrizamide, demonstrated higher accuracy than myelography.
    • CT effectively identified lesions causing cervical radiculopathy.
    • CT can replace myelography in certain patient evaluations.

    Conclusions:

    • CT is a more accurate imaging modality than myelography for cervical radiculopathy.
    • CT can obviate the need for myelography in some cases.
    • Advancements in CT technology will increase its importance in evaluating cervical radiculopathy.
