Computed tomography of the chest

Dr Aditya Shetty et al.

Computed tomography (CT) of the chest is a  cross-sectional evaluation of the heart, airways, lungs and the mediastinum.

Two key methods of image acquisition include:

  • routine CT with 5 mm slice thickness for mediastinum and gross evaluation of lungs
  • high-resolution CT (HRCT) with thin sections (slice thickness of 0.625 to 1.25) for evaluation of secondary lobule of lungs

General indications

 Emergencies
  • chest trauma for evaluation of contusions and rib fractures
  • aortic pathologies (dissection, transection)
  • pulmonary embolism
  • detection of post thoracic surgery complications (mediastinal haematomas, complex pleural collections)
Non-emergencies
  • evaluation of nodules, hilar or mediastinal masses identified on a chest radiograph
  • diagnosis and staging of lung cancer and detection of metastasis from known extrathoracic malignancies
  • assessment of congenital anomalies of the thoracic great vessels
  • characterisation of interstitial lung disease (ILDs)
