Approximately what percent of radiographic retakes are due to motion?

• A. 1%
• B. 5%
• C. 11%
• D. 22%

Answer: (C)

Motion during exposure creates blur that often makes an image nondiagnostic and requires a retake. In radiographic QA data, about 11% of repeat images are attributed to patient motion, so this is a common but not overwhelming cause. This figure reflects how often motion disrupts sharpness across typical imaging populations. To reduce these repeats, use shorter exposure times and higher mA settings when appropriate, provide clear instructions to remain still (and to hold still or breathe as needed for specific projections), and employ immobilization aids or supports. While other factors like positioning or technique errors contribute to repeats, motion remains a notable and addressable contributor, which is why the 11% estimate is commonly cited.
