Why might additional views be ordered beyond standing full-spine AP and lateral views?

• A. To reduce radiation exposure
• B. To evaluate degenerative changes or other pathologies as clinically indicated
• C. To replace standard views
• D. To assess only the cervical spine

Answer: (B)

When you start with standing full-spine AP and lateral views, you’re getting a broad look at alignment and bone structure. Additional views are then ordered only when the clinical exam or initial films suggest something specific beyond what the standard views show. This lets you evaluate degenerative changes or other pathologies that may be present at particular levels or in particular regions. For example, oblique views can better visualize facet joints for arthropathy, while flexion–extension views can reveal instability or abnormal motion not seen on static images. These targeted views are chosen because of clinical indications, not to replace the standard set or to reduce radiation exposure.
