What is the typical radiation dose reduction when using digital radiography compared to conventional film?

  1. 10-20%

  2. 50-70%

  3. 30-50%

  4. 20-30%

The correct answer is: 50-70%

The typical radiation dose reduction when using digital radiography compared to conventional film is substantial, often achieving reductions in the range of 50-70%. This significant decrease is primarily due to the higher sensitivity of digital detectors, which can capture images with less radiation exposure. Digital systems allow for greater flexibility in image processing, enabling radiologists to enhance image quality without needing to increase dose, further contributing to the reduced exposure. While other values presented may reflect some degree of dose savings, they do not encompass the full extent of the advancements offered by digital technology. The 50-70% range is corroborated by research and clinical practice, underscoring the efficacy and safety improvements brought by digital radiography methods.
