Abstract

Purpose: The aim of this study wasto evaluate the comparison of CT arthrography and ultrasonography, confirmed by the arthroscopic finding in patients with rotator cuff disease.
Materials and Methods: We evaluated fifty seven patients with rotator cuff disease underwent CTA and arthroscopy, and twenty eight patients had taken ultrasonographyadditionally. The diagnostic value and prediction for tear size between CTA and ultrasonography were evaluated, as compared to arthroscopic findings.
Results: CTA showed a sensitivity of 86.2% and a specificity of 100% in full thickness tear ofsupraspinatus, a sensitivity of 58.3% and a specificity of 87.8% in partial-thickness tear. CTA demonstrated good diagnostic value for full thickness tear, but there was relatively lower value for partial-thickness tear. Ultrasonography showed a sensitivity of
84.6% and a specificity of 86.7% for diagnosing in full thickness tear, a sensitivity of 84.6% and a specificity of 73.3% in partial-thickness tear. Ultrasonography provided good diagnostic value, but, there is lesser accurate result for prediction of tear size.
Conclusion: CTA showedgood diagnostic tool of detection full-thickness tear of rotator cuff disease and predicting of tear size. Comparing with ultrasonography, CTA was inferior for detection of partial-thickness tear, but, provided better estimation for tear size.
