Answer

When pneumothorax is suspected, confirmation by chest radiography affords additional information beyond confirmation, such as the extent of pneumothorax, potential causes, a baseline study from which to go forward, and assistance with the therapeutic plan.

The following radiologic studies may be used to evaluate suspected pneumothorax:

  • Chest radiography: Anteroposterior and/or lateral decubitus films
  • Contrast-enhanced esophagography: If emesis/retching is the precipitating event
  • Chest computed tomography scanning: Most reliable imaging study for diagnosis of pneumothorax but not recommended for routine use in pneumothorax
  • Chest ultrasonography
