Approximately what percentage of radiographic retakes are due to positioning errors?

• A. 10%
• B. 25%
• C. 50%
• D. 70%

Answer: (B)

Positioning accuracy directly affects whether the anatomy is captured with proper alignment and inclusion. When a patient isn’t positioned correctly—rotated, off-center, or not following anatomical landmarks—the image often fails to meet diagnostic criteria and must be repeated. The best estimate from radiography QA data is that about one in four radiographic retakes result from positioning errors. This reflects that, while exposure factors, motion, and equipment issues also cause repeats, positioning problems commonly account for a sizable portion without dominating all repeats. To reduce these retakes, emphasize solid positioning technique, use immobilization aids, give clear patient instructions, and verify alignment and centering before exposure.
