Which statement accurately describes differences between film-based radiography and digital radiography processing and image manipulation?

• A. Film requires chemical processing; digital uses X-ray film sheets.
• B. Digital radiography can be post-processed.
• C. Digital radiography has no dose considerations.
• D. Digital radiography uses sensors with immediate display and post-processing.

Answer: (D)

Digital radiography brings the image to life on a computer almost instantly because it uses electronic sensors to capture X-ray energy and display the result right away. That immediate display is paired with post-processing capabilities, so you can adjust brightness, contrast, sharpness, apply filters, and measure or annotate the image after acquisition without needing a new exposure. In film-based radiography, the latent image sits on physical film and must go through chemical processing to develop, which makes fixes or enhancements after the fact impossible; you’re limited to what the film reveals at that moment. The statement that mentions post-processing alone is true but narrower, since the defining difference also includes the use of sensors and immediate display that digital systems provide. The other options misstate how digital imaging works or ignore key realities like dose considerations and the absence of film sheets in digital systems.
