Abstract
Objective To compare efficacy of high-frequency ultrasound(US)and MRI in detecting rotator cuff tears.Methods From June 2023 to January 2024,104 patients with unilateral shoulder pain or dysfunction were selected,including 40 males and 64 females,aged from 29 to 87 years old with an average of(59.8±11.9)years old.Methods 7 patients caused by trauma and 97 patients caused by non-trauma.All patients were underwent US and MRI examinations,and taking results of arthroscopic surgery as gold standard;the accuracy rate,positive coincidence rate,negative coincidence rate and total coinci-dence rate of US and MRI in diagnosis of rotator cuff tears were compared,and the diagnostic efficacy between two methods were analyzed.Results Eighty-two patients was diagnosed as rotator cuff tears by arthroscopy(67 patients with partial tears and 15 patients with full-thickness tears),positive rate was 78.8％,accuracy rate of US in diagnosing rotator cuff tear was 29.3％(24/82),and that of MRI was 47.6％(39/82).Moreover,the diagnostic efficacy of MRI was significantly higher than that of US(x2=5.799,P=0.061).According to analysis of tear depth,the accuracy rate of US in diagnosing full-thickness tears was 46.7％(7/15),and that of MRI was 53.3％(8/15),with no statistically significant difference(P=0.715).The accuracy rate of US in diagnosing partial tear was 25.3％(17/67),significantly lower than 46.2％(31/67)of MRI,and the difference was sta-tistically significant(x2=6.362,P=0.012).The total coincidence rates of US,MRI and the combined diagnosis of US+MRI for rotator cuff tear were 51.0％,62.5％and 66.3％respectively.Conclusion MRI is superior to US in diagnosing rotator cuff tears,especially partial tears,and comparable in diagnosing full-thickness tears.When combined diagnosis of US and MRI could fur-ther improve diagnostic efficiency,it is recommended to apply it in combination in clinical practice.关键词
