[The value of high-frequency ultrasound in the diagnosis of duchenne muscular dystrophy in children].

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.
