MRI与高频超声在诊断肩袖损伤中的应用

目的探讨磁共振成像(MRI)与高频超声在诊断肩袖损伤中的应用价值。方法回顾性分析2016年8月~2017年12月间收治的48例肩袖损伤患者临床资料,所有患者均经MRI和高频超声检查。与关节镜检查结果对比,评估MRI、高频超声单独及联合诊断肩袖损伤价值。结果高频超声与MRI诊断完全撕裂、部分撕裂及总体准确率对比,差异无统计学意义(P>0.05);MRI与联合诊断完全撕裂、部分撕裂及总体准确率对比,差异无统计学意义(P>0.05);高频超声与联合诊断完全撕裂准确率对比差异无统计学意义(P>0.05),高频超声部分撕裂、总体诊断准确率低于联合诊断(P<0.05)。结论MRI和高频超声均是诊断肩袖损伤较为准确的影像学技术,联合检查有利于提高高频超声部分撕裂诊断准确性。

Application of MRI and High-frequency Ultrasound in Diagnosing Rotator Cuff Injury

Objective To explore the application value of Magnetic Resonance Imaging(MRI) and high-frequency ultrasound in the diagnosis of rotator cuff injury. Methods The clinical data of 48 patients with rotator cuff injury admitted between August 2016 and December 2017 were retrospectively analyzed. All patients were given MRI and high-frequency ultrasound. The results were compared with the results of arthroscopy, and the value of MRI, high-frequency ultrasound and combined diagnosis for rotator cuff injury was evaluated. Results There was no significant difference between highfrequency ultrasound and MRI in the diagnosis of complete tear accuracy, partial tear accuracy and overall accuracy(P>0.05). There was no difference between MRI and combined diagnosis in diagnosing complete tear accuracy, partial tear accuracy and overall accuracy(P>0.05). There was no significant difference in the accuracy of complete tear between high-frequency ultrasound and combined diagnosis(P>0.05), and the partial tear accuracy and overall accuracy by high-frequency ultrasound were lower than those of combined diagnosis(P<0.05). Conclusion Both MRI and high-frequency ultrasound are accurate imaging techniques for diagnosing rotator cuff injury. Combined examination is beneficial to improve the diagnostic accuracy of partial tear of high-frequency ultrasound.
