FIGURE 2.

The distinction between cystic fibrosis (CF)-related and Aspergillus fumigatus-related structural lung damage in people with CF. The figure represents the difficulty of distinguishing “normal” progression of CF-related lung disease on chest computed tomography (CT) from A. fumigatus infection/bronchitis-related progression and allergic bronchopulmonary aspergillosis (ABPA)-related structural lung disease on top of this progression, and our goal to find the fingerprint for Aspergillus-related lung damage. Note: ABPA and Aspergillus bronchitis can either co-exist or occur separately.
