To study the value of high-frequency ultrasound in the diagnosis of duchenne muscular dystrophy diseases (DMD) in children.
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.
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).
High-frequency ultrasound is valuable in the diagnosis of DMD.
探讨高频超声在小儿杜氏肌营养不良症（DMD）诊断中的价值。
选取8例DMD患儿作为DMD组，10例健康儿童作为对照组。采用高频超声检测两组股直肌的回声及腓肠肌与比目鱼肌之间的间隙。
与对照组相比，DMD组股直肌和腓肠肌回声增强，肌纤维排列不规则，腓肠肌与比目鱼肌之间的间隙增宽（P<0.01）。
高频超声对DMD的诊断具有重要价值。
