EOS Imaging

If your child has been scheduled for EOS imaging, it means their doctor would like a closer look at their spine, hip, or leg.  

What is EOS imaging? 

EOS imaging is a low-dose X-ray system used to look at your child's musculoskeletal system. Images are taken standing up or sitting down, enabling doctors to see your child's natural, weight-bearing posture. The images give doctors a complete view of the spine and lower limbs, all in one image. 

How EOS imaging is used by doctors  

EOS imaging is used to diagnose spine, hip, and leg issues, such as: 

• scoliosis 
• kyphosis 
• limb length discrepancy 
• hip dysplasia 
• bowleg and knock knee conditions 
• balance issues 

EOS is also used for monitoring your child's treatment. An EOS imaging exam uses about one-third of the radiation dose of a conventional X-ray. For this reason, it is used for children who need regular scans to monitor a progressive disease, such as scoliosis. Compared to X-ray or CT, regular EOS imaging will significantly reduce their lifetime radiation exposure. 

How can I help my child prepare for the exam? 

• There is no special preparation for an EOS imaging exam.  
• Please make childcare arrangements for siblings as they will not be allowed into the exam room. 
• If you are pregnant, you will not be allowed in the room during the exam and may wish to have someone else be with your child. 

What will happen during the exam? 

• Check in for your child’s appointment on the Connect patient portal. You may also check in when you arrive at the imaging center.  
• When you arrive for your appointment, your child will be asked to change into a gown. 
• You will be allowed to accompany your child to the exam room.  
• During the exam, your child will stand in a booth for just a few minutes.  
• The EOS system can take pictures of your child’s spine in less than 20 seconds. The entire exam takes about four minutes. 

Are there any risks? 

Your child will be exposed to minimal doses of radiation. The risk is small compared to the benefit of an accurate diagnosis or intervention. 

After the exam 

Your child can immediately resume their normal activities after the exam. A radiologist will analyze the images and share the results with the doctor who requested the exam. Your child’s doctor will then discuss the results with you.
