Radiologic progression with minimal functional decline in cystic fibrosis: Insights from a prospective study

Figure 1 Depicting progressive deterioration of the lungs on high-resolution computed tomography. A: Baseline high-resolution computed tomography (HRCT) shows bronchial wall thickening with subsegmental collapse of the anterior segment of the left upper lobe, along with small centrilobular nodules; B: Follow-up HRCT after one year demonstrates extensive cylindrical, varicoid, and cystic bronchiectasis involving both lungs, with associated bronchial wall thickening and multiple air-space nodules.
