Summary
Photoacoustic imaging (PAI) is an emerging biomedical modality that integrates the advantages of optical contrast and ultrasound imaging depth. Capable of providing morphological, functional, and molecular information, PAI shows significant promise for visualizing human superficial tissue. The goal of this clinical trial is to build a PAI evaluation method for DM skin lesions, explore its application value in assessing DM disease severity and evaluation of treatment response. The main questions it aims to answer are: 1. How to establish a non-invasive PA/US imaging evaluation method for DM skin lesions? 2. Can PAI precisely assess DM disease severity? 3. Can PAI systems predict the treatment response in DM with calcinosis cutis? Participants will receive regular PA/US imaging examinations during five stages of treatment (before treatment, 3 months, 6 months, 9 months and 12 months). And the effectiveness of PA/US in treatment response for DM at different time points will be evaluated.
