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

Summary

# Cone-Beam CT versus Conventional CT for Equine Fetlock Imaging Cone-beam computed tomography (CBCT) has gained traction in equine practice as a potentially more accessible alternative to conventional multidetector CT (MDCT), yet its diagnostic reliability for detailed soft tissue and skeletal anatomy remains incompletely characterised. Bierau and colleagues directly compared CBCT and MDCT image quality by evaluating visualisation of clinically relevant structures throughout the fetlock region, assessing both visibility and practical accessibility of anatomical detail across both modalities. The findings indicate important differences in how clearly each imaging method depicts the various ligamentous, articular, and osseous components of this high-motion joint, with implications for diagnostic confidence in detecting subtle pathology. For practitioners considering investment in CBCT technology or selecting imaging modalities for specific fetlock cases, understanding where each technique excels—and where limitations exist—is essential for appropriate case selection and interpretation. This direct comparison provides evidence-based guidance on the diagnostic utility of CBCT in equine lameness investigation, particularly relevant given the increasing availability and lower cost of CBCT systems compared to conventional CT.
