Diagnosis of dermatomyositis involves a combination of clinical evaluation, laboratory tests, and imaging studies. Key diagnostic tools include:
Blood tests to detect elevated levels of muscle enzymes such as creatine kinase (CK). Electromyography (EMG) to assess electrical activity in muscles. Muscle biopsy to examine muscle tissue for inflammation and other abnormalities. Magnetic Resonance Imaging (MRI) to visualize muscle inflammation.
