摘　　要：目的 探究剪切波弹性成像(SWE)结合CT值在慢性踝关节不稳(CAI)肌肉评估中的应用效果评价。方法回顾性分析2020年10月~2021年12月于承德市中心医院就诊的单侧慢性踝关节不稳患者50例,按照患者健、患侧将其分为健侧组及患侧组,利用CT及SWE对CAI患者的健患侧腓肠肌内侧头、比目鱼肌进行检查,测量CT值(Hu)、杨氏模量值(Kpa)等参数指标。结果 SWE与CT值在慢性踝关节不稳肌肉评估结果中存在明显正相关(腓肠肌pearson相关系数=0.661,P<0.001;比目鱼肌pearson相关系数=0.726,P<0.001),SWE测量杨氏模量值逐渐降低,CT值也逐渐降低,差异有统计学意义(P<0.001)。结论 SWE技术和CT检测对于慢性踝关节不稳肌肉的评估具有相关性,且变化具有一致性。Objective To evaluate the effect of shear wave elastography(SWE) combined with CT in the evaluation of chronic ankle instability(CAI). Methods Retrospective analysis was made on 50 patients with unilateral chronic ankle instability admitted to Chengde Central Hospital from October 2020 to October 2021. The patients were divided into healthy side group and affected side group according to their healthy side and affected side. CT and SWE were adapted to examine the medial head of gastrocnemius muscle and soleus muscle on the healthy side and the affected side of CAI patients. CT values(Hu), Young’s modulus(Kpa) and other parameters were measured. Results There was a significant positive correlation between SWE and CT values in the evaluation results of chronic ankle instability muscles(pearson correlation coefficient of gastrocnemius muscle=0.661, P<0.001;pearson correlation coefficient of soleus muscle=0.726, P<0.001). Young’s modulus measured by SWE gradually decreased, and CT value also gradually decreased, the difference was statistically significant(P<0.001). Conclusion SWE technique and CT examination are correlated in the evaluation of chronic ankle instability muscle, and the changes are consistent.
