Normal Radiographic Anatomy
The Basics
• Radiographs are two-dimensional images of
three-dimensional structures; much
anatomical overlap occurs on radiographs.
Normal Radiographic Anatomy
The Basics
• Five basic densities
–

–
–
–
Metal – bright white
Bone – White
Water/Soft Tissue – Shades of Lighter Gray
Fat – Darker Gray
Air – Black
• Radiolucent = black
• Radiopaque = white
