Characteristic computed tomographic myelography findings in 23 Thoroughbred horses.
Abstract: The purpose of this observational study was to determine the characteristic computed tomographic (CT) myelography findings of cervical vertebral stenotic myelopathy (CVSM) lesions in Thoroughbred horses. A total of 23 Thoroughbred horses (age range, 155-717 days on CT examination; mean, 410.9 days) were analyzed. All 23 Thoroughbred horses underwent unenhanced radiography, radiographic myelography, and CT myelography. Unenhanced radiographs were observed the presence of cervical vertebral malalignment and osseous lesions. Radiographic myelograms were observed for signs of cervical spinal cord compression; additionally, CT myelograms were used to detect cervical vertebral osseous lesions. Ventral compressions were frequently observed in the cranial cervical vertebrae (C2-C4), whereas dorsal compressions were frequently observed in the caudal cervical vertebrae (C5-C7). Furthermore, osseous lesions of the caudal articular process developed more frequently than those of the cranial articular process. CT myelography in Thoroughbred horses is a useful method for detecting CVSM changes.

This study explores the effectiveness of using computed tomographic (CT) myelography to detect cervical vertebral stenotic myelopathy (CVSM) lesions in Thoroughbred horses. Through examining 23 Thoroughbred horses, the research concluded that CT myelography is indeed a useful method for detecting CVSM changes.
Background
- The research was based on an observational study seeking to identify the distinctive CT myelography findings related to CVSM lesions in Thoroughbred horses.
- CVSM is a disease condition that affects the spinal cord in horses, mainly due to the narrowing of the spinal canal.
- The population for the study was 23 Thoroughbred horses, ranging between 155-717 days of age at the time of the CT examination.
Methodology
- The horses underwent a sequence of diagnostic procedures including unenhanced radiography, radiographic myelography, and CT myelography.
- Unenhanced radiographs were examined to observe any presence of cervical vertebral malalignment and bone lesions.
- Radiographic myelograms were analyzed for potential signs of compression on the cervical spinal cord.
- CT myelograms were used to pinpoint any bone lesions in the cervical vertebrae.
Findings
- The results showed that ventral compressions (pressures at the front of the body) were frequently observed in the cranial (front part) cervical vertebrae (C2-C4).
- Dorsal compressions (pressures at the back of the body) were common in the caudal (rear end) cervical vertebrae (C5-C7).
- In addition, they noticed that bone lesions in the caudal articular process (back joint area) developed more often compared to those developing in the cranial articular process (front joint area).
Conclusion
- The study concluded that CT myelography in Thoroughbred horses is a useful method for detecting changes associated with CVSM.
- This method provides detailed and accurate results, particularly in identifying the specific areas of compression and the prevalence of bone lesions.
