Which of the following anatomical parts can be an indicator of the spatial resolution recorded in the radiographic image?

Which of the following anatomical parts can be an indicator of the spatial resolution recorded in the radiographic image?

• A. bowel gas
• B. muscular structures
• C. trabecular bone
• D. fat tissue

Answer: (C)

Spatial resolution is about how well small, closely spaced details can be distinguished in the image. Trabecular bone provides a delicate, high-contrast lattice of thin bony strands; when resolution is good, those trabeculae appear as distinct lines and patterns. If resolution is poor, the fine trabecular detail blurs and the pattern looks more uniform, making the bone appear less detailed. Bowel gas, muscular structures, and fat tissue lack these fine internal patterns and thus don’t reliably reflect how sharp or detailed the image is. So, seeing a clear trabecular pattern indicates better spatial resolution.
