Summary
# Editorial Summary: Multi-Modality Imaging in Equine Tendon Healing Superficial digital flexor tendon (SDFT) injuries remain a significant clinical challenge, yet the diagnostic strengths and limitations of different imaging modalities—ultrasonography, MRI, and CT—have never been systematically compared against actual tissue pathology in a controlled healing model. Johnson and colleagues addressed this gap by prospectively tracking SDFT lesions using all three imaging techniques simultaneously whilst correlating findings with histological and biomechanical tissue analysis at multiple timepoints throughout the healing process. Their results revealed distinct advantages for each modality: MRI excelled at detecting oedema and characterising tissue architecture early in healing, ultrasonography proved superior for identifying fibre disruption and structural heterogeneity, and CT offered valuable complementary information on mineralisation and structural remodelling. For equine practitioners, these findings suggest that imaging protocols should be tailored to the clinical question and healing phase rather than relying on a single modality; combining ultrasonography with MRI appears particularly valuable for comprehensive assessment of SDFT injury, guiding rehabilitation protocols and prognosis with greater precision than any single imaging approach alone.

Practical Takeaways
- •Using multiple imaging modalities (ultrasound, MRI, CT) together provides more complete information about tendon injury than any single modality alone
- •Understanding what each imaging technique actually shows helps interpret results more accurately and make better treatment decisions
- •Serial imaging over time helps monitor healing progress and predict functional recovery in horses with tendon injuries
Key Findings
- •Multi-modality imaging (MRI, CT, ultrasonography) provides complementary diagnostic information for SDFT injury assessment
- •Direct comparison of imaging characteristics to tissue analysis endpoints improves understanding of each modality's diagnostic capabilities
- •Longitudinal imaging assessment enables tracking of tendon healing progression over time
