The chest in profile.
Radiology has been abounding with technological advances since the chest film first became the mainstay in diagnosing thoracic disease, and yet the conventional chest examination has endured as a front-line tool. The ability to perceive structural alterations is facilitated by a solid foundation in anatomy, which should be easy to achieve in a practice environment in which CT has become so commonplace. Not only is knowledge of anatomic nuances important for analysis of conventional radiographs, but it can only be an asset as multiplanar imaging is increasingly utilized and new modalities are developed over time. Some fundamental anatomic variations are revisited here through correlating the perspective provided by the lateral radiograph with the equally common one provided by routine axial CT images.
