Swimmer view to demonstrate:
- a- L/S spine
- b- D/L spine
- c- C/T spine
- d- a&c are correct
- e- a&b are correct
The swimmer view demonstrates the c. C/T spine. Here's why:
Swimmer view:
- It's a modified lateral projection of the cervical spine with the patient lying on their stomach with their head turned slightly to the side.
- This view allows for better visualization of the cervicothoracic junction (C/T junction), which is sometimes obscured by the shoulder on a standard lateral view.
L/S and D/L spines:
- These views are not typically used in standard radiographic examinations.
- L/S (lumbosacral) spine view focuses on the lower spine and sacroiliac joints.
- D/L (dorso-lumbar) spine view captures the middle and lower thoracic and lumbar spine.
- Therefore, the swimmer view is specifically designed to visualize the C/T junction, making c. C/T spine the correct answer.
Additional notes:
- While option d. a&c are correct has some merit as the swimmer view does include a portion of the upper thoracic spine (T1-T2), its primary focus is on the C/T junction.
- Option e. a&b are correct is incorrect as the swimmer view is not used for visualizing the L/S or D/L spine.
