CT imaging of the chest plays an important role in the diagnosis of various pulmonary diseases. Examples of CT signs in the pulmonary diseases that radiologists need to know in routine practice are described in the present essay. The chest CT signs can be categorized into four groups:parenchymal, airway, vascular, and pleural-based signs. It should be noted that some of these are specific to a disease, whereas others help narrow the differential diagnosis. It is very important to know and recognize the signs of characteristic CT findings, not only for diagnosis but also to exclude other diseases. A pattern recognition approach with the appropriate clinical and laboratory findings will certainly help in the diagnosis.
