Normal X-Ray Anatomy Axial and Appendicular Skeleton William Ursprung, DC Slide 2 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 Slide 3 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) Slide 4 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) Slide 5 Cervical Spine Slide 6 Anterior Posterior Open Mouth Slide 7 Anterior Posterior Lower Cervical Slide 8 Lateral Cervical Slide 9 Cervical Oblique Slide 10 Thoracic Spine Slide 11 Posterior Anterior Chest Slide 12 Anterior Posterior Thoracic Spine Slide 13 Lateral Thoracic Spine Slide 14 Lumbar Spine Slide 15 AP Lumbar Slide 16 Lateral Lumbar Slide 17 Pelvis and Hips Slide 18 AP Pelvis Slide 19 Slide 20 Shoulder Slide 21 Normal Shoulder Slide 22 Slide 23 Elbow and Forearm Slide 24 Normal Elbow Slide 25 Slide 26 Forearm Slide 27 Wrist and Hand Slide 28 Normal Wrist Slide 29 Slide 30 Normal Hand Slide 31 Slide 32 Knee Slide 33 Normal Knee Slide 34 Ankle and Foot Slide 35 Normal Ankle Slide 36 Slide 37 Slide 38 Boehlers Angle Slide 39 Normal Foot Slide 40
