Objective.To investigate the MRI findings of acute sports injury of the gastrocnemius muscle and to provide evidence for clinical diagnosis. Methods. The MRI imaging data of 16 cases of gastrocnemius muscle group sports injury were compared, analyzed, and collated. In this paper, the variation of MRI image entropy before and after gastrocnemius muscle injury was studied by using the texture characteristics of the muscle image. Results. The experiment demonstrated that the entropy of MRI images before and after fatigue showed a decrease after muscle tissue was raised; that is, after muscle tissue underwent centrifugal and centripetal contraction. This result is more effective and convenient for nondestructive prediction of the gastrocnemius muscle injury state. Conclusion. MRI can show the site and pathological changes of acute gastrocnemius injury.

腓肠肌急性运动损伤的 MRI 结果

客观的。探讨腓肠肌急性运动损伤的MRI表现，为临床诊断提供依据。方法。对16例腓肠肌群运动损伤患者的MRI影像资料进行比较、分析、整理。本文利用肌肉图像的纹理特征研究了腓肠肌损伤前后MRI图像熵的变化。结果。实验证明，疲劳前后的MRI图像熵在肌肉组织升高后呈现降低；也就是说，肌肉组织经过离心和向心收缩后。该结果对于腓肠肌损伤状态的无损预测更加有效和方便。结论。MRI可以显示急性腓肠肌损伤的部位和病理变化。
