Which statement best describes the difference between digital and conventional film radiography?

• A. Digital radiography requires developing chemicals
• B. Digital radiography offers immediate image display, wider dynamic range, and easier image enhancement with often lower dose
• C. Digital radiography has significantly higher radiation dose
• D. Digital radiography cannot improve image quality

Answer: (B)

Digital radiography uses electronic detectors and computer processing, giving immediate image display, a wider dynamic range, and easier image enhancement, often with a lower patient dose. Instead of waiting for chemical development, the image appears on a monitor right after exposure. The wider dynamic range means more of the varying shades of gray can be captured without losing detail, so clinicians can see both very dark and very bright areas clearly and reduce repeats. Software tools let you adjust brightness and contrast, zoom, magnify, and apply filters to improve visibility after the image is taken. The detectors’ higher efficiency also enables diagnostic-quality images at lower doses in many cases. In contrast, conventional film radiography relies on film-screen technology and chemical processing, has a more limited dynamic range, and provides fewer post-acquisition adjustment options, often requiring careful exposure planning to avoid retakes.
