Which radiographic view is used to evaluate the lower cervical upper thoracic segments on a lateral projection?

• A. Lateral thoracic
• B. AP Chest
• C. Swimmers view
• D. PA skull

Answer: (C)

The main idea is that visualizing the cervicothoracic junction on a lateral radiograph requires removing the shoulder from the line of sight. The swimmers view does exactly this by moving the shoulder girdle away from the spine, typically with the arm on the side of interest raised and extended over the head. This positioning clears the lower cervical and upper thoracic area so you can see the C7–T1 interspace and adjacent segments that are often hidden in a standard lateral view. Compared with other options, the lateral thoracic projection is aimed at the thoracic spine itself and doesn’t optimize the cervicothoracic junction. An AP chest view focuses on the chest and mediastinal structures, not the cervicothoracic transition. A PA skull view targets the skull and upper cervical alignment but again doesn’t provide a good view of the cervicothoracic junction. Swimmers view is the specific technique used to assess that region on a lateral projection because it changes the shoulder position to reduce overlap and reveal the junction clearly.
