PA and Lateral Chest Radiographs

A chest X-ray ("CXR") is one of the most common imaging tests you will encounter as a clinician. Two views (PA and lateral) are obtained at 90 degrees from each other in order to gain an appreciation of dimensionality.

Structures of the chest wall can be evaluated on radiographs. The breast tissue cannot be evaluated on standard CXR due to poor visualization of the breast parenchyma.
