The size of small nodules in the anterior segment of the upper lobe of the right lung did not change much compared with before, (A-B) about 11 mm×11 mm, (C) 13 mm×10 mm, (D) 14 mm×17 mm. The solid composition was the same as before, short burrs could be seen at the edges, and the adjacent pleural stretch was the same as before. The two lungs were scattered in multiple ground glass small nodules, which did not change much compared with before
