Computed tomography (CT) provides detailed imaging of lung structures and diseases like emphysema. Advanced CT techniques also assess lung function, including airway obstruction and regional ventilation.

Area of Science:

  • Pulmonary imaging and diagnostics
  • Thoracic radiology
  • Respiratory system imaging

Background:

  • Computed tomography (CT) is the primary method for assessing pulmonary structure, including airways and parenchyma.
  • CT offers high spatial resolution for visualizing lung pathologies.
  • CT is the gold standard for detecting and characterizing emphysema, showing high concordance with histopathology.

Purpose of the Study:

  • To highlight the capabilities of computed tomography (CT) in pulmonary structure assessment.
  • To demonstrate CT's role in diagnosing airway diseases and emphysema.
  • To showcase advanced CT strategies for evaluating regional pulmonary function.

Main Methods:

  • High-resolution CT for morphological assessment of airways, pulmonary parenchyma, and pathologies.

Related Experiment Videos

  • Paired inspiratory and expiratory CT scans (with/without spirometric triggering) for evaluating small airway obstruction (air trapping).
  • CT-based lung volume segmentation and Cine-CT for visualizing airway motion, regional ventilation, and thoracic dynamics.

    • Main Results:

    • CT effectively visualizes bronchial dilatation, wall thickening, and peripheral airway visibility in airway diseases.
    • CT differentiates between centrilobular, panlobular, and paraseptal emphysema.
    • CT provides functional insights, including air trapping, lung volumes, and dynamic airway/thoracic motion.

    Conclusions:

    • Computed tomography is crucial for the morphological and functional assessment of the lungs.
    • Advanced CT strategies enable detailed regional evaluation of pulmonary structure and function.
    • CT imaging significantly contributes to the diagnosis and characterization of various lung diseases.
