摘要
目的:探讨完全和部分闭合性跟腱撕裂的影像学特征和MRI诊断准确性。方法:回顾性分析39例MRI诊断为跟腱撕裂患者的影像资料,并与手术和/或临床综合诊断结果进行比较,分析MRI诊断完全和部分跟腱撕裂的敏感性、特异性和准确性。结果:39例闭合性跟腱撕裂病例,主要MRI表现为跟腱增粗,腱内信号增高,腱束连续性完全或部分中断,腱周软组织肿胀和积液。本组中MRI诊断完全和部分闭合性跟腱撕裂的敏感度、特异度和诊断符合率分别为100%、92%、95%,阳性预测值为88%,阴性预测值为100%。结论:MRI能够清晰显示跟腱撕裂的形态及内部结构,可以准确诊断完全和部分性跟腱撕裂,有利于指导临床选择合理的治疗方案。
Objective：To evaluate the MRI characteristics in the differential diagnosis of complete or partial closed laceration of Achilles tendon and its accuracy. Methods： MRI findings in 39 cases with closed laceration of Achilles tendon were retrospectively reviewed and compared with the findings of surgery or clinical diagnosis. The sensitivity, specificity and accuracy of MRI in the differential diagnosis of partial or complete laceration were evaluated. Results： Of the 39 patients, the main MRI findings were thickening and increased of internal signal intensity, partial or complete discontinuity of Achilles tendon,with surrounding tissue swelling and fluid accumulation. The sensitivity, specificity, accuracy, positive predictive value,and negative predictive value of MRI in the diagnosis of partial or complete closed laceration of Achilles tendon were 100% ,92% ,95% ,88% and 100% respectively. Conclusion：MRI can clearly displayed the shape and the internal structure of Achilles tendon, it can be used to differentiate complete from partial laceration of-the tendon with 92 % accuracy, which is helpful in the treatment planning.
