    Serial alveolography allows for detailed lung imaging, revealing functional and morphological changes. This technique differentiates normal lungs from emphysema and fibrotic lung diseases.

    Area of Science:

    • Pulmonary Medicine
    • Radiology
    • Medical Imaging

    Background:

    • Indirect lymphography via serial alveolography is a novel technique.
    • This method produces radiographic images similar to barium-imbibed lung preparations.

    Purpose of the Study:

    • To introduce and evaluate a new serial alveolography technique for indirect lymphography.
    • To assess the capability of this method in demonstrating serial radiographic changes and local contrast medium clearance.
    • To explore the simultaneous assessment of morphological and functional lung aspects.

    Main Methods:

    • Development of serial alveolography using a contrast medium for indirect pulmonary lymphography.
    • Application of the technique to visualize lung morphology and function.
    • Comparison of radiographic features between normal lungs and those with chronic pulmonary emphysema or fibrotic diseases.

    Main Results:

    • Radiograms comparable to barium-imbibed preparations of resected lung were achieved.
    • The procedure successfully demonstrated serial radiographic changes and local contrast medium clearance.
    • Significant differences in radiographic features were observed between normal lungs and lungs affected by emphysema or fibrotic diseases.
    • Simultaneous morphological and functional (pulmonary lymph-related) examinations were feasible.

    Conclusions:

    • Serial alveolography is a practical and effective method for indirect pulmonary lymphography.
    • This technique allows for rapid, simultaneous assessment of lung morphology and function.
    • The method shows potential in differentiating between normal lungs and various pathological conditions like emphysema and fibrotic lung diseases.
