Which statement is true when evaluating a lateral thoracic spine radiograph?

• A. Vertebral bodies are superimposed and there is no rotation
• B. Spinous processes are clearly divergent
• C. Diaphragms not visible
• D. Intervertebral disc spaces must be seen in thoracic spine

Answer: (A)

A lateral thoracic spine radiograph should show a true lateral projection, where the vertebral bodies are superimposed one over another and there is no rotation of the patient. This consistent alignment indicates the beam is truly from the side and that the image isn't distorted by turning the patient toward or away from the camera. When rotation is present, the vertebral bodies don’t line up neatly and the spinous processes lose their expected posterior alignment, giving a distorted look. The diaphragms should be visible on a properly exposed lateral view, and while intervertebral disc spaces can be seen, their appearance is not the defining criterion of a good lateral image. So the key indicator is vertebral bodies superimposed with no rotation.
