【 摘 要 】

Aim of the work: To assess the role of sonoelastography (SE) and conventional ultrasound (US) in detection of rotator cuff (RC) lesions as compared to magnetic resonance imaging (MRI). Patients and methods: This study included 36 patients with > 3 months (chronic) shoulder pain and limitation of movement examined by US, SE and MRI. US and SE findings of RC tendinopathy and tears were compared to MRI as a gold standard. Results: The mean age of the patients was 47.8 ± 10.04 years, 20 males and 16 females. The mean duration of symptoms was 6 ± 2.9 months. On MRI, 16 (44.4%) were diagnosed as RC tendinopathy, 10(27.8%) showed partial tears and 10(27.8%) full thickness tears. On US, tendinopathy was detected in 15(41.7%), partial tears in 8(22.2%) and full tears in 9 (25%). SE could identify tendinopathy in 15(41.7%), partial and full tears in 9 (25%) cases each. Compared to MRI, US sensitivity for tendinopathy detection was 81.3% with 95% specificity and 88.9% accuracy while for partial tears, its sensitivity, specificity and accuracy were 80%, 92.3% and 88.9% respectively. In full thickness tears its sensitivity, specificity, accuracy were 90%, 100% and 97.2% respectively. Compared to MRI, SE sensitivity for tendinopathy detection was 93.8%, 95% specificity and 94.4% accuracy while for partial tears, its sensitivity, specificity and accuracy were 90%, 92.3% and 91.7% respectively and in full tears were 90%, 100%, 97.2% respectively. Conclusion: SE is more sensitive than conventional US in detection of rotator cuff tendinopathy and partial thickness tears as compared to MRI.
