1. Artifacts are commonly seen on DXA images 2. DXA artifacts may be internal or external to the patient 3. It is important to recognize which internal artifacts influence BMD measurement 4. Some artifacts may be eliminated by reanalysis of the scans by the technologists 5. Reporting of artifacts should be standardized  

1. Internal versus external artifacts; 2. Spine DXA artifacts: fractures, degenerative disease, orthopedic hardware; 3. Hip DXA artifacts: osteoarthritis, heterotopic bone, pannus, orthopedic hardware; 4. Forearm DXA artifacts: remote fracture, patient motion, orthopedic hardware; 5. Whole body DXA artifacts: breast prostheses, pacemakers, orthopedic hardware; 6. Vertebral Fracture Assessment (VFA) artifacts: diaphragm, Schmorl’s nodes, pannus, diffuse idiopathic skeletal hyperostosis (DISH); 7. Internal artifacts that matter: fractures, metastatic disease, Paget’s disease, fibrous dysplasia, inflammatory arthritis, spondyloarthritis; 8. Internal artifacts that do not matter: vascular clips, gallbladder clips, gallstones, renal stones, vascular calcifications; 9. Best practice approach to reporting artifacts; 10.
