Trial Summary

Do I need to stop my current medications for this trial?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the treatment EOS imaging system?

The EOS imaging system is effective for evaluating and monitoring conditions like scoliosis and osteoarthritis, offering accurate images with low radiation exposure. It provides detailed 3D images of the skeleton, which helps in assessing spinal and limb balance and skeletal maturity.12345

Is the EOS imaging system safe for humans?

The EOS imaging system is generally considered safe for humans as it delivers a very low radiation dose compared to conventional X-ray systems, which reduces the risk of radiation-induced cancer, especially in adolescents undergoing repetitive imaging.12567

How does the EOS imaging system treatment differ from other treatments for skeletal structure analysis?

The EOS imaging system is unique because it provides full-body 2D and 3D images with a very low radiation dose, capturing both front and side views simultaneously, which is not possible with conventional X-rays. This allows for a comprehensive analysis of the skeletal structure, particularly useful for conditions like scoliosis and osteoarthritis, while minimizing radiation exposure.12345

What is the purpose of this trial?

A study of the skeletal structure and how the structure changes over time. The aim of the study is to evaluate the skeleton in 10 year increments to determine an understanding of the normal skeleton as a person ages. By using x-ray analysis, a new low dose x-ray system (EOS) can be used to evaluate the whole body to see changes in the bone structure over time. Subjects will be asked to undertake one x-ray analysis of their whole body skeletal structure. There will be 25 male and 25 female subjects per decade. The averaging of the measured skeletal parameters will provide information on changes over time generating a standardized expectation of general changes in skeletal structure as participants age.

Treatment Details

Interventions

  • EOS imaging
Trial Overview The study uses EOS imaging—a low dose full-body x-ray system—to observe changes in skeletal structure every decade to understand normal aging patterns. With an equal number of male and female volunteers per age group (25 each), it aims to create a standard expectation of skeletal changes as people get older.

Findings from Research

The EOS imaging system provides accurate grading of osteoarthritis (OA) in the knee, comparable to conventional radiographs, based on a study of 142 patients using the Kellgren and Lawrence score and OARSI system.
EOS images demonstrate excellent reliability for measuring joint space and grading OA, but may not always clearly show subchondral sclerosis, suggesting that conventional radiographs should still be used alongside EOS for comprehensive assessment.
Is the EOS imaging system as accurate as conventional radiography in grading osteoarthritis of the knee?Koliogiannis, VKA., Brandlhuber, M., Messerschmidt, V., et al.[2021]
The EOS(®) 2D/3D X-ray imaging system shows comparable or better spinal image quality than traditional X-ray methods, while significantly reducing radiation exposure—over five times lower for certain spine views.
However, the current evidence is limited, with no reported patient health outcomes, indicating a need for further clinical studies to assess how EOS(®) impacts patient management and outcomes in orthopaedic conditions.
A systematic review of the clinical effectiveness of EOS 2D/3D X-ray imaging system.Wade, R., Yang, H., McKenna, C., et al.[2021]
The innovative EOS® low-dose X-ray biplanar imager provides highly reproducible 3D measurements of spinal deformities, with an intraclass correlation coefficient (ICC) greater than 0.9, indicating excellent reliability.
Intra- and inter-observer reproducibility for 3D measures was significantly better than for 2D measures, with mean absolute differences of less than 2° or 2 mm, making 3D assessments more accurate for evaluating sagittal balance.
Sagittal balance measures are more reproducible when measured in 3D vs in 2D using full-body EOS® images.Okamoto, M., Jabour, F., Sakai, K., et al.[2020]
