Compared with film, digital radiography offers which advantage?

• A. It requires chemical processing.
• B. It has a narrower dynamic range.
• C. It offers immediate display, post-processing, and a wider dynamic range.
• D. Retakes always require more exposure.

Answer: (C)

Digital radiography offers immediate display, post-processing, and a wider dynamic range, which together improve workflow and image quality compared to film. The immediate display means the image is available right after exposure, speeding diagnosis and reducing the need for patient recall. Post-processing tools let you adjust brightness and contrast, sharpen edges, and reduce noise to enhance details without repeating the procedure. A wider dynamic range means the detectors can capture a broader spectrum of exposure levels, preserving detail in both very light and very dark areas, so fewer images are ruined by exposure errors and less repeat imaging is needed. While film requires chemical processing and has limited latitude, digital systems provide flexibility that makes these advantages possible. Retakes don’t automatically require more exposure in digital radiography because you can often adjust the existing data to improve diagnostic quality.
