Summary
# Editorial Summary Cone beam computed tomography (CBCT) has gained traction in human and small animal orthopaedic diagnostics, yet its application in equine practice remains underexplored, particularly for the complex carpal anatomy. Hagenbach and colleagues directly compared CBCT imaging against the established gold standard of multidetector computed tomography (MDCT) using equine cadaveric carpal specimens, systematically evaluating image quality, anatomical detail visibility, and practical limitations across both modalities. Key findings revealed that CBCT provided diagnostic visualisation of major osseous and soft tissue structures comparable to MDCT in many respects, though MDCT maintained superior soft tissue contrast resolution and artefact management in certain regions—particularly relevant for ligamentous and cartilaginous pathology assessment. For equine practitioners, these results suggest CBCT could serve as a viable, potentially more accessible alternative to MDCT for certain carpal investigations, though clinicians should recognise its specific strengths (bone detail, lower radiation dose) and limitations when formulating imaging protocols for suspected carpal injuries. The findings merit further clinical validation to establish evidence-based guidelines for CBCT application in working diagnoses of carpitis, chip fractures, and other performance-limiting carpal conditions.
