EOS is used to image children with skeletal alignment issues such as scoliosis. This imaging system was born out of Nobel Prize-winning technology. Riley at IU Health is the first hospital in Indiana to acquire an EOS. There are less than 40 EOS machines in the United States. Using very low-dose X-rays, a single high-quality scan allows doctors to see problems with alignment, posture and the spine.
EOS has many benefits for children. The most significant benefit is the marked reduction in radiation dose. Children with alignment issues tend to undergo multiple imaging scans while they grow. The low amount of radiation used for an EOS scan greatly reduces the risks associated with repeated imaging tests.
In addition, multiple images are taken very quickly without your child having to change position, reducing the stress of the exam. Each exam takes between five and 20 seconds, and unlike other imaging technologies, children may breathe during an EOS exam without affecting the quality of the images.
The EOS also allows for three-dimensional modeling of the spine in the natural weight-bearing position for complex surgery planning.
Children who can stand alone for the images stand in what resembles a large phone booth. Your child will need to stand still while the X-rays are taken. However, your child will not need to hold his or her breath. Front and lateral views will be taken at the same time without the need to change positions. This is accomplished by the use of two X-ray tubes that move together.
At Riley at IU Health, there is no additional charge for EOS. Patients will be charged the same as a typical X-ray.
