Application of imaging techniques in diagnosis and severity assessment of dermatomyositis / 中华皮肤科杂志

ABSTRACT

Dermatomyositis is an autoimmune disease involving the skin and muscles. At the onset of dermatomyositis, it is difficult to make an early diagnosis due to atypical clinical manifestations and lack of serological markers. Skin and muscle lesions are associated with disease activity and prognosis in patients with dermatomyositis or clinical amyopathic dermatomyositis. Computed tomography, magnetic resonance imaging, ultrasonography, dermoscopy and other imaging techniques may be used to assess skin and muscle involvements, which can not only improve the accuracy of early diagnosis of dermatomyositis, but also provide important reference for the assessment of disease activity and prognosis.
