Approximately what % of retakes are due to errors in positioning?

• A. 10%
• B. 25%
• C. 50%
• D. 70%

Answer: (B)

Positioning accuracy directly affects whether the anatomy is captured in the correct place, aligned, and without unwanted rotation or distortion. Approximately one quarter of retakes occur because the part isn’t positioned correctly, so the image doesn’t meet the exam’s diagnostic requirements. This 25% figure is a common QA benchmark, reflecting that errors in how the patient or part is set up are the most frequent single reason for repeats, even when exposure factors are appropriate. Other retake causes like improper exposure, motion, or equipment issues still occur, but positioning errors are typically the leading contributor. To reduce these retakes, focus on clear patient instruction, reliable use of positioning aids, verification of anatomical landmarks, and consistent positioning protocols.
