Thoracic Spine

These radiographs are for evaluation of the thoracic spine. Although there is detail in the chest cavity that will be the focus of subsequent sessions, at this time use these images to evaluate spinal anatomy and associated structures. At times it can be challenging to locate a particular vertebral level. "Counting ribs" on radiographs is a skill that improves with practice. For these two images it is best to locate the T12 vertebra (most inferior vertebra articulating with a rib) and count from that location.

Identify the following:

1. clavicles (PA view)

2. vertebral body T12

3. intervertebral disc T10-11

4. left pedicle T7 (PA view)

5. right transverse process T9 (PA view)

6. spinous process T2 (PA view)
