Cone-beam computed tomography produces images of numerically comparable diagnostic quality for bone and inferior quality for soft tissues compared with fan-beam computed tomography in cadaveric equine metacarpophalangeal joints.

The study compares the quality of images produced by Cone-beam computed tomography (CBCT) and Fan-beam computed tomography (FBCT) in imaging the metacarpophalangeal joint in equine cadavers. The findings reveal that the CBCT and FBCT produce excellent images for bone evaluations, but the FBCT outperforms CBCT in terms of soft tissue evaluation.

Research Objective and Methodology

• The aim of this research was to evaluate the effectiveness of CBCT and FBCT in imaging the metacarpophalangeal joint in equine cadavers, with a particular focus on bone and soft tissue visualizations.
• This was a prospective, descriptive, and exploratory study where the researchers employed the use of CBCT and FBCT in their evaluations.
• Reliance on both types of imaging techniques was pivotal for thorough assessments given their unique strengths in producing numerically comparable quality of images for different tissues.

Research Findings

• The study determined that satisfaction scores were high with both CBCT and FBCT when it came to bone evaluation. Both technologies were highly effective and provided similar quality results in this context.
• However, FBCT was found to be superior in soft tissue evaluation, indicating its more effective nature for imaging in tissues other than the bone.
• The findings also highlighted that preference testing for bone was observer-dependent, meaning that some observers may prefer one method over the other based on their specific situations or requirements.

Implications and Possible Applications

• This study serves as a foundation for further studies that aim to evaluate image quality using CBCT on live horses.
• The findings can also provide insights to veterinarians and equine health experts for selecting the most suitable imaging method depending on the tissues to be evaluated, which would enhance their diagnostic accuracy.
• Additionally, this study’s results can inform the development of more effective imaging tools in the future, potentially leading to the enhancement of equine healthcare.
