Small animal myelography is a safe and effective diagnostic tool for neurologic disorders, utilizing newer, less neurotoxic contrast agents like iohexol. Recognizing abnormal myelographic patterns is key for accurate diagnosis and treatment planning.

Area of Science:

  • Veterinary Neurology
  • Diagnostic Imaging

Background:

  • Myelography is crucial for diagnosing small animal neurologic disorders.
  • Older contrast agents posed higher neurotoxic risks.

Purpose of the Study:

  • To outline safe and effective myelography techniques for small animals.
  • To recommend appropriate contrast media and highlight diagnostic interpretation.

Main Methods:

  • Review of small animal myelography procedures.
  • Evaluation of newer myelographic contrast media (iohexol, iopamidol).
  • Discussion of diagnostic interpretation and therapeutic considerations.

Main Results:

  • Small animal myelography can be performed safely without specialized equipment.

  • Newer agents like iohexol (180-300 mg I/mL) are recommended over metrizamide.
  • Abnormal myelographic patterns are critical for diagnosis; normal studies can occur in diseased patients.
  • Epidurography is effective for canine lumbosacral disease, correlating with surgical findings.
  • Conclusions:

    • Small animal myelography is a valuable, accessible diagnostic method.
    • Iohexol is the preferred contrast agent.
    • Careful interpretation and availability of anticonvulsants are essential for patient safety and diagnostic accuracy.
