The diagnosis of emphysema. A computed tomographic-pathologic correlation.

C Bergin, N Müller, D M Nichols

    The American Review of Respiratory Disease
    |April 1, 1986
    PubMed
    Summary

    Computed tomography (CT) accurately diagnoses emphysema. CT scans correlated well with pathology, proving more effective than pulmonary function tests for assessing emphysema severity.

    Area of Science:

    • Pulmonology
    • Radiology
    • Medical Imaging

    Background:

    • Emphysema diagnosis relies on imaging and pulmonary function tests.
    • Accurate assessment of emphysema severity is crucial for patient management.

    Purpose of the Study:

    • To evaluate the diagnostic accuracy of computed tomography (CT) for emphysema.
    • To compare CT findings with pathological grading and pulmonary function tests.

    Main Methods:

    • Computed tomography (CT) scans were performed on 32 patients pre-surgery.
    • CT scans were visually assessed for emphysema by radiologists and a physician.
    • Pathological emphysema grading from resected lung specimens was correlated with CT scores and pulmonary function tests.

    Main Results:

    Related Experiment Videos

    • Significant correlation was found between pathological emphysema grade and preoperative CT scores (whole lung: r ≥ 0.63, p < 0.001).
    • CT outperformed pulmonary function tests in predicting emphysema.
    • CT effectively distinguished moderate emphysema from normal lungs.

    Conclusions:

    • Computed tomography (CT) is a valuable tool for assessing emphysema presence and severity.
    • CT offers a more accurate assessment of emphysema compared to pulmonary function tests.
