摘　　要：目的:探讨超声和MRI对腓肠肌内侧头训练伤的诊断效能。方法:回顾性分析2013年1月至2022年1月经临床初步诊断为下肢训练伤怀疑腓肠肌内侧头损伤70例研究对象的临床资料,所有患者均完成超声及MRI检查,根据临床综合诊断结果比较二者的灵敏度、特异度、准确度。结果:70例训练伤临床最终确诊48例腓肠肌内侧头损伤,22例无腓肠肌损伤。其中腓肠肌组织损伤19例,肌筋膜损伤水肿和组织间隙积液28例,肌腱和腱鞘损伤26例,腱止点末端病6例。超声及MRI对腓肠肌内侧头训练伤损伤诊断敏感性分别为85.4%(41/48)、97.9%(47/48),准确率分别为84.3%(59/70)、95.7%(67/70),MRI检查的诊断准确率、敏感性高于超声检查(P<0.05),特异性比较差异无统计学意义(P>0.05)。结论:MRI相比超声对腓肠肌内侧头训练伤的准确率、敏感性较高,具有重要的临床应用价值。Objective:To investigate the diagnostic efficacy between magnetic resonance imaging(MRI)and ultrasound for training injury of medial head of gastrocnemius muscle.Methods:Clinical data of 70 cases with lower limb training injury suspected to be in the medial head of gastrocnemius muscle from Jan 2013 to Jan 2022 were retrospectively analyzed.All patients were examined by ultrasound and MRI,and their sensitivity,specificity and accuracy according to the final clinical diagnosis was compared.Results:Of the 70 cases of training injury,48 cases were finally diagnosed as medial head injury of gastrocnemius muscle,and 22 cases had no gastrocnemius injury.And there were 19 cases of gastrocnemius tissue injury,28 cases of myofascial injury edema and tissue interstitial effusion,26 cases of tendon and tendon sheath injury,and 6 cases of tendon insertion enthesiopathy.The sensitivity of ultrasound and MRI in the diagnosis of training injury of medial head of gastrocnemius muscle were 85.4%(41/48),97.9%(47/48)and the accuracy was 84.3%(59/70),95.7%(67/70),respectively.The diagnostic accuracy and sensitivity of MRI were higher than those of ultrasound(P<0.05).There was no significant difference in specificity between the two methods(P>0.05).Conclusion:MRI has higher accuracy and sensitivity compared with ultrasound in the diagnosis training injury of medial head of gastrocnemius muscle,which has important diagnostic value.
