What percent of all repeats come from ABD region films?

• A. 25%
• B. 40%
• C. 50%
• D. 60%

Answer: (B)

The main idea here is understanding how repeat radiographs are distributed among different body regions. ABD region films (abdomen) pose particular imaging challenges—patients may be large, have variable bowel gas, and require precise positioning and centering to get a usable image. Motion, under- or overpenetration, and field coverage issues are common with abdominal exams, so they tend to generate a sizable share of repeats.

Forty percent reflects that ABD repeats are a significant portion of all repeats, but not the majority, since other regions (like chest, pelvis, or extremities) also contribute. The other percentages would under- or overestimate ABD’s role given typical repeat-distribution data.

To reduce repeats from the ABD region, focus on solid positioning, accurate centering, appropriate exposure factors for the patient’s size, and clear patient instructions to minimize motion.
