View original scientific description
The purpose of this research is to collect medical imaging data to allow for the comparison of bone mineral density measurements from two low-dose x-ray exams.
Interventions
RADIATION
EOSedge imaging
Full body or full spine image
Primary outcome measures
AP Spine BMD Precision
Time frame: 1 day
Calculation of EOSedge BMD from the 2 exams will be post-processed from the bi-planar EOSedge 2E radiographs, and is measured in g/cm² surface mass on four lumbar vertebrae (L1-L4) in the anteroposterior (AP) projection. Precision error will be calculated from the 2 exams.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
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

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
