Area of Science:

  • Pulmonary Medicine
  • Radiology
  • Diagnostic Imaging

Background:

  • High-resolution computed tomography (CT) is established for infiltrative lung disease diagnosis.
  • Recent emphasis highlights CT scan's utility in diagnosing airway and obstructive lung diseases.

Purpose of the Study:

  • To review the application of expiratory CT scans in diagnosing lung disease.
  • To detail various CT scan techniques, findings, and their use in obstructive diseases.

Main Methods:

  • Utilizing dynamic expiratory or postexpiratory CT scans.
  • Often combining expiratory CT with inspiratory high-resolution CT scan studies.
  • Reviewing normal and abnormal findings on expiratory CT scans.

Main Results:

  • Expiratory CT scans, particularly when combined with inspiratory scans, are effective for obstructive lung disease diagnosis.
  • The technique aids in assessing the severity and characteristics of airway obstruction.

Conclusions:

  • Expiratory CT scanning is a valuable tool for diagnosing and assessing obstructive lung diseases.
  • This modality complements traditional CT techniques, offering enhanced diagnostic capabilities for airway-related pathologies.
