Can be used to quickly determine if edema is present in the lungs or effusion is present in the pleural cavity, thus differentiating it from "dry" lung diseases such as asthma.  Presence of nodules is indicative of fungal or neoplastic disease. If the lungs are dry, there is no left sided congestive heart failure present by definition.
