Bone Mineral Density Precision Study

Inclusion Criteria

• Subjects indicated for full-spine or whole-body radiography via EOSedge 2E biplanar imaging (e.g., in the preoperative evaluation of spine and/or other orthopaedic conditions)
• Male or female subjects who are at least 20 years of age at the time of imaging acquisition
• Written informed consent obtained from the potential subject or the subject's legal representative and ability for the subject to comply with the requirements of the study

Exclusion Criteria

• Subjects who have been administered contrast agents or radionuclides within 7 days prior to scheduled radiographic imaging (EOS and DXA)
• Subjects who are pregnant or wanting to become pregnant during the timeframe of study participation (due to risks associated with radiographic imaging)
• Subjects with a BMI ≥ 35 kg/m2
• Subjects known to have severe degenerative changes or fracture deformity in the measurement area (i.e., lumbar spine L1-L4, bilateral femoral neck/trochanter; note that unilateral femoral evaluation is acceptable), as defined by the Investigator's determination of the likelihood of reasonably assessing bone mineral density of those areas
• Subjects known to have implants, hardware, devices, or other foreign material in the measurement area (i.e., lumbar spine L1-L4, bilateral femoral neck/trochanter; note that unilateral femoral evaluation is acceptable)
• Subjects unable to attain correct position and/or remain motionless for the measurement (e.g., subjects unable to stand unassisted in the EOS unit, or to lie appropriately in the DXA scanner)
• Subjects known to have extra or missing lumbar vertebrae (i.e., more or fewer than 5 mobile lumbar segments)
• Subjects participating in another clinical study which may compromise this study's results or compliance with this study's procedures
• Subjects with presence of a condition or abnormality that in the opinion of the Investigator would compromise the safety of the subject or the quality of the data
