Does ap lateral chest r ray show the lungs as well?

To a degree: An ap (front to back) and lateral (self explanatory) chest xray displays a fairly good screening view of the lung, ribs, scapula, diaphragm, parts of the spine and shoulder joints, but the resolution of lung tissue increases with ct scanning with contrast and mri. The chest xray however gives enough detail to determine most conditions though perhaps not in the earliest stages.
