The following radiographs show normal thoracic spine anatomy.

AP View

Lateral View
|
- The routine examination consists of AP and lateral views.
- The lateral view is obtained during quiet respiration to blur out the overlying pulmonary vessels.
- In the normal spine, the anterior cortex should have a smooth margin in the lateral view.
- Also on lateral view, vertebral bodies and disc spaces get larger with caudal progression.
- On the AP view, a paravertebral soft tissue line can usually be seen. Any displacement of this line
can be a sign of swelling helpful for the diagnosis of injury.
