  1. Putting all this information together, we get our two rules of pleural effusions. If pleural thickening is visible, the fluid is an exudate, and it may be an empyema, but it is not translate. If no pleural thickening is visible, the fluid may be an exudate or a transudate, but it's not an empyema.

    Are pleural CT appearance features reliable in distinguishing transudates from exudative effusions?
    Additional pleural CT appearance features such as fluid loculation, pleural thickness, and pleural nodules are not reliable in differentiating exudates from transudates, although their prevalence is higher among exudative effusions. Address correspondence to Y. Abramowitz ([email protected]).

    What is the value of CT evaluating pleural fluids?
    Start the course now! The value of CT evaluating pleural fluids is that it can help differentiate the nature of the fluid, even though it cannot tell us the cause. There are three kinds of pleural fluids of concern, transudates, exudates, and empyemas.

    How are exudative pleural effusions classified?
    Categorization of the effusions is based on laboratory characteristics of the fluid (see table Criteria for Identifying Exudative Pleural Effusions). Whether unilateral or bilateral, a transudate can usually be treated without extensive evaluation, whereas the cause of an exudate requires investigation.

    Are pleural effusions a transudate or exudate?
    MATERIALS AND METHODS. We retrospectively analyzed 100 pleural effusions in patients who underwent chest CT and diagnostic thoracentesis within 48 hours of each other. On the basis of Light's criteria, effusions were classified as exudates or transudates using laboratory biochemistry markers.

    Pleural Effusion: Characterization with CT Attenuation Values and CT

    ajronline.org
    What are pleural effusions?
    Pleural effusions are collections of fluid within the pleural space. The term is usually reserved for collections of serous fluid and therefore excludes hemothorax, chylothorax, and pyothorax (empyema). Effusions may cause mass effect on the adjacent lung causing collapse, breathlessness, and respiratory compromise.

    How accurate is a CT thorax for a pleural effusion?
    CT thorax is more accurate for diagnosis and is better at characterising the size and location of a pleural effusion. Typical findings of normal pleural fluid are as follows: Transudative pleural effusions are defined as effusions that are caused by factors that alter hydrostatic pressure, pleural permeability, and oncotic pressure.
