The common pulmonary parenchymal disease processes in ICU patients include hydrostatic pulmonary edema, acute respiratory distress syndrome (ARDS), atelectasis, pneumonia, aspiration, and pulmonary hemorrhage. Indistinctness of pulmonary vasculature is subtle but often the most useful radiographic sign of early interstitial edema in ICU patients. The CT findings of hydrostatic pulmonary edema include smooth interlobular septal thickening, ground-glass opacities, consolidation, and pleural effusions ( Fig. 7.4) . The diagnosis of pneumonia in ICU patients is often challenging as the airspace opacities seen on chest radiographs in these patients can be caused by atelectasis, aspiration, pulmonary hemorrhage, noninfectious lung inflammation (e.g., drug reaction), pulmonary edema, or ARDS [12] . The radiographic abnormalities commonly seen with aspiration are patchy ill-defined ground-glass opacities, nodular opacities, or consolidation in the dependent regions of the lungs (Fig. 7.10 ).	./cache/cord-017771-g72qaoub.txt	./txt/cord-017771-g72qaoub.txt
