Relationship between anxiety and depression, dyspnea severity, and pulmonary function in connective tissue disease-associated interstitial lung disease

Figure 1 Detection of high-resolution computed tomography imaging indicators in typical cases. A and B: Diffuse grid shadow with ground-glass shadow in middle and lower fields of both lungs, and subpleural distribution was dominant (at enrollment); C and D: The ground-glass opacity was partially absorbed, but fibrous bands were increased in the basal segment, suggesting early fibrosis (6^th month); E and F: Shows further confluency of the grid shadows, with the formation of traction branches and the appearance of honeycomb-like changes with continuous progression of fibrosis (12^th month). Scan parameters: Siemens Somatom Definition Flash, 1.0 mm layer thickness, 120 kVp, 200-250 mAs. Double blind evaluation of quantitative lesion extent.
