The abdominal region accounts for approximately what percentage of all diagnostic X-ray examinations performed?

• A. 10%
• B. 25%
• C. 50%
• D. 75%

Answer: (B)

The idea is to recognize how often different body regions are imaged. The abdomen accounts for about one-quarter of all diagnostic X-ray examinations. This reflects the wide range of abdominal concerns that prompt imaging—from acute abdominal pain and bowel obstruction to stones, appendicitis, and trauma—so abdomen studies are a staple in many radiology practices. Chest exams are typically the most frequent single category, with extremities also contributing a large share, placing abdominal imaging at roughly 25% rather than a larger proportion. Keep in mind that the exact percentage can vary by hospital or patient population, but about a quarter is a common estimate used to illustrate imaging distribution.
