What is EOS imaging?

​

EOS imaging is a low-dose, weight-bearing X-ray technology. It can simultaneously take full-body, frontal and lateral (side view) images of the skeletal system of a patient in a standing or sitting position, using significantly less radiation than traditional X-rays or CT scans. A typical EOS scan at HSS has a radiation dose equivalent to about one-third that of the dose of a conventional X-ray of the same body parts.

​

The results gives you a detailed picture and measurements of the patient's lower limb, pelvic angles, spine position and leg length. The scan is bulk-billed on Medicare.

​

Using EOS, two dimensional (2D) and three-dimensional (3D) orthopedic images can be produced to assist doctors with the diagnosis and treatment of medical conditions of the spine, hips and knees.

What is EOS imaging used for?

​

EOS imaging is used for anatomical assessment of the entire musculoskeletal system and is invaluable for evaluating the following conditions:

• scoliosis

• kyphosis

• limb length discrepancy

• balance and posture complications

• hip dysplasia

• bowleg and knock knee conditions

​

EOS is a pediatric-friendly scan. For some children and teens who require frequent imaging to monitor progress of a chronic skeletal or musculoskeletal condition (such as scoliosis), multiple doses of radiation from standard X-rays may unnecessarily increase their life-long radiation exposure. EOS can effectively replace standard X-rays in these instances and thereby reduce any risks associated with radiation exposure over their lifetime.
