At the bedside, chest radiography remains the reference for lung imaging in

critically ill patients. However, radiographical images are often of

limited quality

• Movements of the chest wall

• Film cassette posterior to the thorax

• X-ray beam originating anteriorly, at a shorter distance than

recommended and not tangential to the diaphragmatic cupola .

Mistaken assessment

of :

c

• Pleural effusion

• Alveolar consolidation

• Alveolar-interstitial

syndrome
