Visualization of anatomical structures in the carpal region of the horse using cone beam computed tomography in comparison with conventional multidetector computed tomography.

Abstract: In the diagnostics of orthopedic diseases in the horse, diagnostic imaging often plays a decisive role. Cone beam computed tomography (CBCT) imaging is used in both human and small animal medicine and becoming increasingly popular. To see whether CBCT imaging can be useful in the diagnosis of orthopedic diseases of the carpal region of the horse and to explore possible limitations we compared CBCT images with multidetector computed tomography (MDCT) images of the carpal region of equine cadaveric specimens. Unassigned: Twenty-eight forelimbs from fifteen horses, slaughtered for reasons unrelated to this study, were examined. Native and contrast enhanced CBCT and MDCT scans were performed. Anatomical structures were blindly evaluated by three independent experienced observers using a visual scoring system previously reported and adapted to the equine carpal region. A descriptive evaluation was carried out as well as Spearman's rank correlation and interobserver agreement was shown by percent agreement (PA). Unassigned: Visualization of osseous structures was excellent in both MDCT and CBCT. Articular cartilage could only be assessed in contrast enhanced scans whereby MDCT showed a slightly better visualization than CBCT. Soft tissue structures were generally difficult to assess. An exception were the medial and lateral palmar intercarpal ligament, which could not be visualized in native but were well visualized in contrast enhanced scans in both MDCT and CBCT images. Unassigned: For the evaluation of osseous structures and some intraarticular ligaments after contrast enhancement, CBCT serves as a reliable diagnostic imaging modality for the equine carpal region. However, soft tissue structures and cartilage are imaged more reliably using MDCT.

Summary

This research summary has been generated with artificial intelligence and may contain errors and omissions. Refer to the original study to confirm details provided. Submit correction.

This research investigates the use of cone beam computed tomography (CBCT) in diagnosing orthopedic diseases in horses compared to conventional multidetector computed tomography (MDCT). The study indicates that while CBCT proved effective in evaluating bone structures and some ligaments, MDCT was more reliable in imaging soft tissue structures and cartilage.

Research Methodology

  • The research used twenty-eight forelimbs from fifteen horses that were slaughtered under circumstances not associated with the study.
  • Both Native and contrast-enhanced CBCT and MDCT scans were performed on these limbs.
  • Three independent experienced observers, who were not informed about the specifics of the scans, evaluated the anatomical structures blindfolded, using a visual scoring system that was previously reported and adjusted for the equine carpal region.
  • A descriptive analysis was carried out, with both Spearman’s rank correlation applied to determine the correlation of findings and interobserver agreement was demonstrated by percent agreement (PA).

Research Findings

  • When it comes to visualizing bone structures, both MDCT and CBCT performed excellently.
  • The articular cartilage could only be assessed with contrast-enhanced scans, with MDCT providing slightly better visualization than CBCT.
  • In general, soft tissue structures were challenging to evaluate.
  • A unique case was the medial and lateral palmar intercarpal ligament, which could not be visualized in native scans but were well visible in contrast-enhanced scans in both MDCT and CBCT images.

Conclusion

  • The CBCT can reliably diagnose osseous structures and some intraarticular ligaments after contrast enhancement in the equine carpal region.
  • However, for soft tissue structures and cartilage, MDCT produces more reliable images.
