Radiologic signs in the thorax

Abstract

Knowledge of the main radiology signs may help recognizing patterns of diseases and cover the main possible differential diagnosis. Many of the signs use metaphoric terms and some are told highly suggestive of a specific disease. Some signs may be recognized in conventional chest radiography and in computed tomography, while others are just applicable in one of these methods. Along with the use of the correct semiology and terminology, knowledge of these signs helps to achieve the correct interpretation of chest radiography findings. In this article, we’ve made a brief review of the main thoracic radiology signs.
