Abstract: Most pneumothoraces are demonstrated on fully inspired erect posteroanterior (PA) chest X-ray (CXR). Expiratory films may have a role in the clinical management of patients with a small respiratory reserve in whom pneumothorax is suspected and not demonstrated on the inspiratory film. PA CXR can be used for the diagnosis of spontaneous and ­nonspontaneous pneumothoraces. When digital radiography is used, for most authors, a 2.5-lp/mm spatial ­resolution is satisfactory to detect a pneumothorax.

Keywords: radiography, computed tomography, pneumothorax, posteroanterior chest X-ray
