    Study Notes

    Diagnostic Tools for Compressive HNPE

    • Contrast-enhanced CT (CE-CT) has a sensitivity of 91% and a specificity of 100% for diagnosing compressive HNPE.
    • CE-CT characteristics of compressive HNPE include:
      • Well-demarcated hypoattenuating lesion just above the intervertebral disc space
      • Rim enhancement
      • Variable degrees of spinal cord compression
    • When MRI is not available, myelo-CT is commonly used to:
      • Improve visualization of spinal cord boundaries
      • Better define the myelographic pattern
      • Suspect spinal cord compression
    • Myelo-CT has a higher diagnostic yield compared to plain or intravenous CT in acute onset myelopathies, such as intervertebral disc herniations.
    • Consistent myelo-CT findings of compressive HNPE in dogs include:
      • Presence of compressive HNPE in all but two of 15 cases
      • Utility in distinguishing from other spinal cord pathologies when combined with clinical information
