肌肉损害不仅见于皮肌炎,而且还见于其它结缔组织病。但肌肉损害常由于化验检查、肌电图和肌肉活检不能提供确切的资料而不易确诊。为评价结缔组织病的肌肉受累情况,作者对40例结缔组织病患者做了~(201)铊肌肉扫描检查,并与肌电图、血生化和肌肉活检等检查方法做了比较。这40例结缔组织病患者包括皮肌炎7例,系统性红斑狼疮7例,进行性系统性硬皮病12例,CREST 综合征2例,单肢性硬皮病3例,局限性硬皮病
Muscular damage is seen not only in dermatomyositis, but also in other connective tissue diseases. However, muscle damage often due to laboratory tests, EMG and muscle biopsy can not provide accurate information and not easily diagnosed. To assess muscle involvement in connective tissue disease, the authors performed ~ (201) thallium muscle scan in 40 patients with connective tissue disease and compared them with EMG, blood biochemistry and muscle biopsy tests. The 40 patients with connective tissue disease include dermatomyositis in 7 cases, systemic lupus erythematosus in 7 cases, progressive systemic sclerosis in 12 cases, CREST syndrome in 2 cases, unilateral scleroderma in 3 cases, localized scleroderma disease
