Summary
Ultrasound B-scan imaging quantifies fiber bundle density (FBD) in equine superficial digital flexor tendons (SDFTs). This method objectively distinguishes healthy SDFTs from injured ones by measuring FBD differences.
Area of Science:
- Veterinary Imaging
- Equine Tendon Biomechanics
Background:
- Ultrasound B-scan imaging is crucial for assessing equine superficial digital flexor tendon (SDFT) health.
- Objective characterization of SDFT structure and injury is needed for accurate diagnosis.
Purpose of the Study:
- To develop and validate a shock filter algorithm for quantifying fiber bundle density (FBD) in equine SDFTs.
- To assess the utility of FBD measurements in differentiating healthy from injured SDFTs.
Main Methods:
- A novel shock filter algorithm combined with morphological operations was applied to ultrasound B-scan images.
- Fiber bundle fascicles were extracted and quantified to calculate mean FBD.
- FBD values were analyzed across three metacarpal sites in normal and injured SDFTs.
Main Results:
- Normal SDFTs exhibited highest FBD proximally and lowest distally.
- Mean FBD was significantly lower in injured SDFTs (39 ±7) compared to normal SDFTs (51 ±9) (p = 0.004).
- The algorithm successfully identified structural differences indicative of tendon lesions.
Conclusions:
- Ultrasound B-scan imaging with FBD quantification is an effective tool for characterizing equine SDFT anatomy.
- This imaging technique shows promise for clinically assessing SDFT integrity and detecting injuries.
