Summary
# Editorial Summary: Non-skeletal Scintigraphy of the Horse Whilst gamma scintigraphy is well-established in equine practice for detecting skeletal pathology, Archer and colleagues highlight its broader diagnostic potential across non-skeletal organ systems—a capability that remains underutilised in clinical settings. By systematically reviewing the indications and evidence base for non-skeletal applications, the authors demonstrate that scintigraphy can effectively investigate dental disease, localise inflammatory foci, identify vascular lesions, and assess soft-tissue pathology including muscle and tendon injury, alongside functional imaging of the respiratory, gastrointestinal, and other organ systems. A critical finding emerging from their review is that many non-skeletal techniques lack robust validation through prospective clinical studies, meaning their diagnostic accuracy and clinical reliability remain incompletely characterised. For equine professionals considering scintigraphy as a diagnostic tool, this work emphasises the importance of understanding both the capabilities and current evidence limitations of each technique before committing to the procedure on clinical and economic grounds. Investment in prospective validation studies would significantly strengthen the evidence base and enable more confident interpretation of results when diagnosing complex, non-skeletal conditions.

Practical Takeaways
- •Scintigraphy offers diagnostic capability beyond bone imaging for investigating soft tissue, organ, and vascular disease when conventional imaging is inconclusive
- •Clinicians should request well-validated non-skeletal scintigraphic protocols and be cautious interpreting results from techniques lacking prospective validation studies
- •Economic and clinical value of non-skeletal scintigraphy varies by technique; seek evidence-based guidance before committing to these investigations
Key Findings
- •Gamma scintigraphy can investigate disease in virtually any organ system depending on radiopharmaceutical and imaging sequence selection
- •Non-skeletal scintigraphic applications in horses include dental disease, inflammatory lesions, vascular pathology, and assessment of organ physiological function
- •Many non-skeletal scintigraphic techniques in horses lack full validation and require prospective studies to establish clinical utility
