| 目的 应用实时剪切波弹性成像（SWE）技术评价先天性肌性斜颈（CMT）患儿胸锁乳突肌（SCM）。方法 对130例初诊CMT患儿进行二维超声检查，根据二维超声表现确定其二维分型（Ⅰ~Ⅳ型），采用SWE测量患侧、健侧SCM弹性模量平均值（Emean）；对患侧二维超声表现分型与Emean进行相关性分析；运用ROC曲线计算各型的Emean截断值。结果 CMT患儿各二维超声表现分型健侧与患侧SCM的Emean差异有统计学意义（P<0.05）。各二维超声表现分型与患侧Emean呈正相关（rs=0.76，P<0.05）。利用ROC曲线获得Ⅰ~Ⅳ型Emean截断值分别为15.35 kPa、29.60 kPa、38.05 kPa及47.80 kPa。结论 SWE技术可客观量化显示SCM硬度，评估CMT患儿胸锁乳突肌纤维化严重程度，具有较高临床价值。 |

| Objective To observe the application value of shear wave elastography (SWE) in analyzing the sternocleidomastoid (SCM) of congenital muscular torticollis (CMT).Methods Totally 130 CMT children were recruited. Two-dimensional ultrasonography was performed to identify the classification of CMT (Ⅰ-Ⅳ types). Then Emean of the affected side and the healthy side of SCM were measured with SWE, and the correlation between two-dimensional ultrasonographic types and Emean of the affected side of SCM was analyzed. ROC curve was used to calculate the Emean truncation value of each tape.Results The difference between the affected side and the healthy side of SCM of 130 children was statistically significant (P<0.05). There was strong positive correlation between two-dimensional ultrasonographic types and Emean (rs=0.76, P<0.05). According to ROC curve, the Emean truncation values of Ⅰ-Ⅳ types were 15.35 kPa, 29.60 kPa, 38.05 kPa and 47.80 kPa, respectively.Conclusion SWE technology can objectively quantify the hardness of SCM, and evaluate the severity of myofibrosis in children with CMT, therefore having significant clinical value in diagnosis of CMT. |
