Computed tomography of the trachea: normal and abnormal

G Gamsu, W R Webb

    AJR. American Journal of Roentgenology
    |August 1, 1982
    PubMed
    Summary

    Computed tomography (CT) effectively images the trachea, aiding in diagnosing conditions like saber-sheath trachea and neoplasms. However, CT offers limited advantages over conventional methods for detecting tracheal stenosis.

    Area of Science:

    • Radiology and Imaging
    • Thoracic Medicine
    • Medical Diagnostics

    Background:

    • The trachea, a vital airway, requires accurate imaging for diagnosis and treatment planning.
    • Computed tomography (CT) is a key imaging modality for thoracic structures.
    • Understanding normal and abnormal CT appearances of the trachea is crucial for patient care.

    Purpose of the Study:

    • To evaluate the utility of computed tomography (CT) in visualizing the trachea and surrounding mediastinal structures.
    • To describe normal CT variations and assess CT's role in diagnosing various tracheal diseases.
    • To compare CT findings with conventional imaging techniques for tracheal abnormalities.

    Main Methods:

    • Retrospective analysis of CT scans from 50 healthy individuals and 39 patients with tracheal diseases.
    • Detailed description of normal CT anatomy of the trachea and adjacent structures.
    • Correlation of CT findings with clinical data and outcomes for patients with tracheal pathology.

    Main Results:

    • CT effectively demonstrated tracheal anatomy and variations.
    • For tracheal stenosis, CT provided no additional diagnostic information compared to tomography and tracheography.
    • CT accurately characterized saber-sheath trachea, including cartilage abnormalities and expiratory collapse.
    • CT excelled in defining intraluminal tumors, airway compression, and extratracheal extension in neoplastic disease.
    • CT findings were valuable for assessing resectability of tracheal neoplasms and planning radiation therapy.

    Conclusions:

    • Computed tomography is valuable for evaluating tracheal neoplasms and planning treatment.
    • CT aids in diagnosing specific conditions like saber-sheath trachea.
    • CT offers limited added benefit over conventional methods for tracheal stenosis detection.
