EOS Low-dose radiation scanner

Why we measure it - While the scientific community is still studying how much radiation affects the growing body, we know excessive radiation exposure increases the risk of developing a cancer. We make every effort to use as low a radiation dosage as possible so that we can get the diagnostic image needed for treatment without compromising long-term radiation risks.

A child diagnosed with scoliosis at age 10 needs two X-rays per year until age 17 when he or she reaches skeletal maturity.


What this means
- Patients will receive significantly less radiation if they have all their scoliosis imaging done in an EOS machine versus using plain films. EOS radiation is up to 10 times less than conventional x-rays.

About the data - Radiation exposure with plain film (assuming 10 units of radiation per dose) = approximately 160 units. Radiation exposure with EOS (assuming 1 unit of radiation per dose) = approximately 16 units.

How we provide the best care

  • Children's Hospital of Wisconsin is one of two pediatric hospitals in the nation with an EOS low-dose radiation scanner. Doctors mainly use the scanner to help treat children with scoliosis (a curved spine). Families already are traveling across the country for this cutting-edge care.
  • One of the most important advantages of using the EOS scanner is the large decrease in radiation dose - up to 10 times less than a regular X-ray and up to 99 percent less than a CT (computed tomography) scan of the spine.
  • Another advantage is that EOS images also provide sharper detail, helping doctors better decide the right course of treatment and, over time, measure the results of that treatment.
