MRI诊断肩袖损伤及撕裂程度的临床应用观察
Clinical Observation of MRI in Diagnosing Rotator Cuff Injuries and Assessing the Degree of Tears
摘要
Abstract
Objective:To explore the application efficacy of MRI in diagnosing rotator cuff injury and assessing the tear degree.Methods:A retrospective analysis was conducted on the data of 183 patients with shoulder injuries in our hospital.All patients underwent a magnetic resonance imaging(MRI)examination,using arthroscopy as the gold standard to investigate the diagnostic value of MRI for rotator cuff injuries.The detection of injuries and the degree of tears in different tendons of the rotator cuff were examined,and the de-viation in the measurements of tendon tear sizes in full-thickness tears by MRI compared to arthroscopy was analyzed.Results:Arthroscopic examination revealed 136 positive cases of rotator cuff injuries out of 183 pa-tients,and 47 negative cases.MRI detected 134 positive cases and 49 negative cases,with a diagnostic sensi-tivity of 95.59%(130/136),specificity of 91.49%(43/47),accuracy of 94.54%(173/183),positive predictive value of 97.01%(130/134),negative predictive value of 87.76%(43/49),and a Kappa value of 0.859.Arthroscopy diagnosed a total of 373 injuries in 183 patients,including 136 supraspinatus tendon injuries,122 infraspinatus tendon injuries,and 115 subscapularis tendon injuries.The detection rate of MRI for supraspinatus,infraspinatus,and subscapularis tendon injuries was significantly lower than that of arthros-copy(P<0.05).Among the 136 patients with rotator cuff injuries,there were 45 cases of full-thickness tears and 91 cases of partial tears.The accuracy of MRI in diagnosing full-thickness tears was 93.33%(42/45)and 94.51%(86/91)for partial tears,with a total accuracy of 94.12%(128/136),which was significantly lower than that of arthroscopy(P<0.05).The accuracy of MRI in measuring the retraction degree and tear span of the tendon ends in full-thickness tears was 86.67%(39/45)and 82.22%(37/45),respectively.Conclusion:MRI has a high diagnostic value for both rotator cuff injuries and the degree of tendon tears,pro-viding a reliable preoperative diagnostic basis for rotator cuff injuries,and is worth promoting in clinical appli-cation.关键词
