6 Questions
What is the sensitivity of contrast-enhanced CT (CE-CT) for diagnosing compressive HNPE?
91%
What is the main characteristic of compressive HNPE on CE-CT?
A well-demarcated hypoattenuating lesion with rim enhancement
When is myelo-CT commonly used in diagnosing spinal cord compression?
When MRI is not available
What is the benefit of using myelo-CT over plain or intravenous CT in acute onset myelopathies?
It has a higher diagnostic yield
What is the limitation of this case series in evaluating the benefit of myelo-CT over contrast-enhanced CT?
It is a retrospective descriptive case series
What is the conclusion of this case series regarding the use of myelo-CT in diagnosing compressive HNPE?
Myelo-CT is useful in diagnosing compressive HNPE, especially when combined with clinical information
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
Explore the role of Contrast-enhanced CT and MRI in diagnosing compressive HNPE, including their characteristics and sensitivity. Learn about the diagnostic tools used when MRI is not available.
