Which practice best counteracts exposure creep in digital radiography?

• A. Regularly reviewing and adjusting exposure protocols
• B. Keeping protocols unchanged after initial setup
• C. Lowering all exposure settings universally
• D. Relying solely on automatic exposure control

Answer: (A)

Exposure creep happens when technique factors gradually rise over time to maintain image quality as equipment and practice evolve. In digital radiography, detectors can mask changes in technique, so small drift in performance or perception can lead to higher exposures unless protocols are kept up to date. Regularly reviewing and adjusting exposure protocols ensures the charts reflect current detector behavior, patient populations, and dose goals, keeping image quality diagnostic while minimizing patient dose. This proactive upkeep catches drift early and keeps technique consistent with ALARA principles. Leaving protocols unchanged allows drift to accumulate as equipment ages, software updates occur, and clinical expectations shift. Lowering all exposure settings universally would sacrifice image quality and diagnostic accuracy, rather than preventing creep. Relying solely on automatic exposure control isn’t enough either, because AEC results depend on current protocol targets and setup; without periodic review, dose optimization can miss the mark and creep can continue.
