对29例神经肌肉疾病(包括多种肌营养不良,多发性肌炎,多种神经原性肌肉病变与DMD可能递体)的120处随意肌进行了临床与超声检查。其中20块受检肌,在超声检查的相应部位,又接受了肌活检。结果提示:1.除结缔组织增生与脂肪浸润外,肌纤维坏变与间质内细胞浸润,也是超声图像异常的病理基础。2.超声可检出肌力尚未减退的病肌。3.超声检查可以帮助随诊病况,但敏感性不强。4.或有助于初选DMD递体,其阳性率待定。 Clinical and sonographic examination was performed on 120 random muscles in 29 neuromuscular diseases, including various muscular dystrophy, polymyositis, various neurogenic muscular lesions and possible DMD. 20 of which were examined muscle, the corresponding parts of the ultrasound examination, but also received a biopsy. The results suggest: 1. In addition to connective tissue hyperplasia and fatty infiltration, myofibrosis and interstitial infiltration of cells, but also the pathological basis of abnormal ultrasound images. 2. Ultrasound can detect muscle strength has not diminished sick muscle. 3. Ultrasound can help follow-up conditions, but the sensitivity is not strong. 4. Or contribute to the primacy of DMD, its positive rate to be determined.
