Abstract:
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.
