Magnification

In projectional radiography ("X-ray") of the thorax (chest), the estimated geometric magnification factor is generally between 1.05 and 1.40,[1] meaning that measurements made in the image will be this much larger than the real distance in the patient. Therefore, compare to other structures (such as pleural fluid reaching half way to hilar level) where possible rather than giving numbers.

Normal anatomy

  • A normal posteroanterior (PA) chest radiograph.

  • Normal lateral chest radiograph.

  • Projectionally rendered CT, showing the transition of thoracic structures between the anteroposterior and lateral view.

Diseases

Regions

  • Ribs
  • Sternoclavicular joint
