A chest CT scan might be used in patients with aspiration pneumonia if a chest x-ray is not conclusive. CT findings may include lobar consolidation, ground-glass opacities, bronchiectasis, atelectasis, pleural effusion, and consolidation. A chest CT can also help to assess reasons for therapy failure and complications, such as lung abscess, and pleural effusions.
