目的：探讨高频超声在小儿杜氏型肌营养不良（DMD）疾病中的辅助诊断价值。方法：将8例DMD患儿作为DMD组，10例健康儿童作为对照组，用高频超声检测所有研究对象的股直肌肌肉回声及腓肠肌与比目鱼肌间隔。结果：与对照组相比，DMD组股直肌及腓肠肌回声增强，且肌肉纤维排列紊乱，两侧腓肠肌与比目鱼肌的间隔均明显增宽（P<0.05）。结论：使用高频超声检测肌肉形态的变化可为DMD的诊断提供依据。
Abstract
OBJECTIVE: To study the value of high-frequency ultrasound in the diagnosis of duchenne muscular dystrophy diseases (DMD) in children. METHODS: Eight children with DMD were enrolled as DMD group and 10 healthy children as the control group. The echogenicity of the rectus femoris muscle and the gap between the gastrocnemius and soleus muscles in the two groups were detected by high-frequency ultrasound. RESULTS: Compared with the control group, rectus femoris and gastrocnemius muscles in the DMD group showed increased echogenicity and their muscle fibers were arranged irregularly, and the gap between the gastrocnemius and soleus muscles became wilder (P<0.01). CONCLUSIONS: High-frequency ultrasound is valuable in the diagnosis of DMD.
