J Med Imaging Radiat Oncol. 2014 Feb;58(1):64-74. doi: 10.1111/1754-9485.12031. Epub 2013 Feb 18.

Abstract

In this article we revisit, with the help of images, those classic signs in chest radiography described by Dr Benjamin Felson himself, or other illustrious radiologists of his time, cited and discussed in 'Chest Roentgenology'. We briefly describe the causes of the signs, their utility and the differential diagnosis to be considered when each sign is seen. Wherever possible, we use CT images to illustrate the basis of some of these classic radiographic signs.

Keywords: CT; chest; imaging; radiography; sign.
