Normal X-Ray Anatomy

Axial and Appendicular

Skeleton

William Ursprung, DC


Lesson Objectives

  • Identify anatomical structures on plain film radiographs

  • Identify the views commonly used to radiograph the skeletal system

  • Utilize a basic search pattern to screen plain film radiographs for pathology


Basic Rules for Interpretation

  • Plain films are a 2 dimensional gray scale image of a 3 dimensional anatomical structure

  • Four basic densities

    • Metal = very bright (white)

    • Bone = bright (white)

    • Water/soft tissue = (various shades of gray)

    • Air = dark (black)


Basic Rules for Interpretation

  • Rule of thumb for radiographs: min. of 2 views that are offset by 90° for any body part

  • ABOLTS search pattern

    • A = anatomy

    • B = breaks or step defects in the cortex

    • O = opacities (ie blastic lesion, impacted fx)

    • L = lucencies (ie lytic lesion, displaced fx)

    • T= trabecular architecture

    • S = soft tissues (swelling, mass, fascial planes)
