Computed tomography (CT) effectively visualizes acute respiratory distress syndrome (ARDS) lung abnormalities like consolidation and cysts, which are often missed on chest X-rays. CT findings, including lung cysts, correlate with higher ARDS mortality rates.

Area of Science:

  • Radiology
  • Pulmonology
  • Critical Care Medicine

Background:

  • Acute Respiratory Distress Syndrome (ARDS) is a severe lung condition with high mortality.
  • Chest radiography is commonly used for ARDS diagnosis but has limitations in visualizing certain lung pathologies.
  • Computed tomography (CT) offers higher resolution imaging of lung parenchyma.

Purpose of the Study:

  • To describe the CT features of ARDS patients.
  • To compare CT findings with chest radiographs.
  • To assess the impact of CT findings on patient management and outcomes.

Main Methods:

  • Retrospective review of CT scans from 28 ARDS patients.
  • Analysis of imaging findings including consolidation, cysts, abscesses, and empyema.

  • Correlation of CT findings with chest radiographs and patient mortality.

    • Main Results:

    • CT demonstrated diffuse consolidation, multifocal patchy disease, lobar/segmental involvement, and lung cysts (swiss-cheese appearance).
    • These CT findings were often not apparent on chest radiographs.
    • Overall mortality was 72.7%; patients with lung cysts had a trend toward higher mortality (87.5%).
    • Unexpected findings included basilar lung abscesses and empyema.
    • CT provided additional information in 15/28 patients, altering management in 5.

    Conclusions:

    • CT imaging provides crucial details of ARDS lung pathology, including cysts, which are often missed by chest X-rays.
    • The presence of lung cysts on CT may indicate a poorer prognosis in ARDS patients.
    • CT can significantly aid in ARDS diagnosis, management, and prognostication.
