我们对222例转诊至儿科肌肉门诊的新患者进行了前瞻性研究，以评估超声成像的诊断价值。在不了解临床表现或其他检查结果的情况下解读超声扫描。肌营养不良产生了一个明亮的斑点图案增加的回声从肌肉，而脊髓性肌萎缩症表现出中度增加的肌肉回声和相关的肌肉萎缩。急性皮肌炎产生了适度的回声增加，随着超声波束相对于肌纤维的方向而明显变化。脑源性肌张力减退、普拉德-威利综合征、韧带松弛和其他“非神经肌肉”原因的儿童超声扫描正常。在8例患者中，超声扫描显示股四头肌的单个成分的选择性参与的程度惊人，这为选择性穿刺活检提供了相当大的诊断帮助。儿童超声扫描的主要优点是无创和愉快的门诊程序，可以在多个部位轻松完成。对神经肌肉疾病儿童的筛查有一定的参考价值。
A prospective study was done on 222 consecutive new patients referred to our pediatric muscle clinic to assess the diagnostic value of ultrasound imaging. Ultrasound scans were interpreted without knowledge of clinical presentation or results of other tests. Muscular dystrophy produced a brightly speckled pattern of increased echo from the muscle, whereas spinal muscular atrophy showed a moderate increase in muscle echo and associated muscle atrophy. Acute dermatomyositis produced a moderate increase in echo that varied markedly with the direction of the ultrasound beam in relation to the muscle fibres. The ultrasound scan was normal in children with hypotonia of cerebral origin, Prader Willi syndrome, ligamentous laxity, and other "nonneuromuscular" causes. In eight patients ultrasound scanning showed a striking degree of selective involvement of individual components of the quadriceps muscle, which provided considerable diagnostic help for selective needle biopsy. Ultrasound scanning in children has the major advantage of being a noninvasive and pleasant out-patient procedure, which can be readily done on multiple sites. It is a valuable screening test in the investigation of children with neuromuscular disorders.
