🔍 Key Findings Summary
- Study Design: Prospective case series of 52 scans from 44 dogs with CCL injury.
- Main Technique: 16-slice CTA; evaluated by 3 observers with varying experience; validated against surgical mini-medial arthrotomy findings.
- Diagnostic Metrics (Reading 2):
- Sensitivity: 1.00 (Observers 1 & 2), 0.93 (Observer 3)
- Specificity: 0.78–0.91
- Positive Likelihood Ratio: Up to 10.71
- Negative Likelihood Ratio: As low as 0.08
- Accuracy: 90%+ for all in Reading 2
- Observer Effect: Significant improvement between first and second reading for less experienced observers (p < 0.05); learning curve evident.
- Meniscal lesions found:
- 9/12 in suspected late meniscal injury cases
- 19/40 in newly diagnosed CCL cases
- Most common = bucket handle tears
- Conclusion: Multidetector CTA is a clinically useful, non-invasive tool for identifying medial meniscal lesions in dogs with CCL disease.
