Radiographic interpretation of atelectasis bears particular importance in the setting of aspiration, which involves added dangers of infection, inflammation and interstitial edema. While the consequences of pulmonary aspiration are ultimately a function of the type, volume and acidity of aspirated material, the overall result is often diminished gas exchange and loss of lung volume. Regardless of the mechanism, this loss of lung volume frequently occurs in a predictable manner that can be assessed using various diagnostic tools, of which the quickest and most direct tool is likely the chest X-ray CXR. Essential to such interpretation with CXR is an understanding of specific lobar patterns of atelectasis and the radiographic findings associated with these patterns. Similarly, it is important to recognize the pathophysiology of aspiration and the capacity for aspirated fluid to produce lobar atelectasis in a given patient.
