What is the typical repeat rate in radiographic practice?

• A. 1-2%
• B. 3-4%
• C. 5-10%
• D. 15-20%

Answer: (C)

Repeat rate is the portion of radiographs that must be retaken because of technique, positioning, exposure, or patient factors. It reflects how efficiently a radiology department can produce acceptable images on the first try, and minimizing it is important to keep patient dose down and maintain throughput. In modern digital radiography, many issues can be corrected after acquisition, so repeat rates tend to be modest rather than extremely high, but repeats still occur from things like patient motion, incorrect positioning, or wrong exposure settings. A typical benchmark often seen in everyday practice falls in the 5–10 percent range. Rates well below this suggest excellent technique and protocol adherence; rates much higher indicate identifiable problems in technique, equipment, or workflow that should be addressed. So the best-supported range for a typical repeat rate is around 5–10 percent.
