目的探讨超声弹性成像组织弥散定量分析在军训小腿肌肉损伤中的诊断价值。方法选取军训致小腿肌肉损伤22例作为研究对象,以正常小腿肌肉作为自身对照,分析肌肉损伤与自身对应部位正常肌肉二维图像与弹性成像的图像特点;运用超声弹性成像组织弥散性定量分析软件评价肌肉组织的硬度,对照正常肌肉和肌肉损伤各弹性参数的变化。结果肌肉损伤组11个参数中,应变均值、蓝色区域所占百分比、复杂度较对侧均存在统计学意义(P<0.001),标准差、偏度、峰度、对比度、均等性、杂乱度、一致度、相关性无统计学意义(P>0.05),提示损伤后肌肉弹性应变均值减低、蓝色区域所占百分比及复杂度增加,肌肉硬度增加。结论超声弹性成像弥散性定量分析在二维超声的基础上能提供客观、准确的肌肉硬度的定量数据及图像信息,提高了肌肉局部损伤及小的肌纤维撕裂诊断敏感性,此技术运用于军训肌肉损伤诊断能为早期诊断肌肉损伤并指导康复训练提供客观依据。 Objective To investigate the diagnostic value of tissue elastography quantitative elastography in military training calf muscle injury. Methods Twenty-two cases of muscular injuries caused by military training were selected as the study objects. The normal calf muscles were taken as self-control to analyze the image characteristics of two-dimensional images and elastic images of normal muscles with muscle damage and their corresponding parts. Ultrasound elastography was used to measure tissue dissemination quantitative analysis software The hardness of the muscle tissue was evaluated, and the change of each elasticity parameter of the normal muscle and muscle damage was compared. Results Among the 11 parameters of muscle injury group, the average value of strain, percentage of blue area and complexity were statistically significant (P <0.001), standard deviation, skewness, kurtosis, contrast, homogeneity and clutter Degree, consistency and correlation were not statistically significant (P> 0.05), suggesting that the mean value of muscle elastic strain decreased, the percentage and complexity of blue region increased, and the hardness of muscle increased. Conclusion Ultrasound elastography quantitative diffusion analysis can provide objective and accurate quantitative data of muscle stiffness and image information on the basis of two-dimensional ultrasound and improve the diagnostic sensitivity of muscle local lesion and small muscle fiber tear. This technique is applied to military training Muscle injury diagnosis can provide an objective basis for the early diagnosis of muscle damage and guide rehabilitation training.
