Lungenröntgen (Thoraxröntgen, Cor-Pulmo)

Preparation: none


The lung x-ray is taken in two planes,with the patient erect; in the case of a recumbent patent, in a single plane. Deep inhalation is important during exposure. The only exception is suspicion of pneumothorax (air in the lung). Then the image is taken during deep inhalation.


Brief fluoroscopy may be done when the outcome is unclear.


Occasionally, computer tomography may also be required in order to clarify suspicious findings.


Pathological processes in the lungs, heart and diaphragm can be assessed on the basis of the images:

  • Inflammation of the lungs (pneumonia)

  • Pneumothorax (air in the lung)

  • Pleural effusion (fluid in the lung)

  • Lung enemphysa (hyperinflation of the lung)

  • Pleurisy

  • Heart disease (shape, size)
  • Pulmonary congestion (with impaired heart function)

  • Pulmonary fibrosis

  • Benign and malignant tumours

  • Oncological aftercare (cancer aftercare)

  • Diaphragm (elevated/lowered diaphragm, diaphragmatic hernia)
