What to Know About an EOS Scan

What Is EOS Imaging?  

Understanding your body’s alignment starts with getting the right imaging. That’s where EOS comes in. An EOS scan is a specialized, low-dose X-ray that captures detailed images of your spine and legs, while in a natural standing position. 

Why You Might Need an EOS Exam 

EOS imaging is used to diagnose and track changes of the spine, hips, and legs, such as: 

  • Scoliosis evaluation - Measures spine curvature and tracks changes over time 

  • Leg length differences - Checks if one leg is shorter than the other 

  • Alignment problems – Shows whether your hips, knees, and ankles are properly lined up 

 

What Can You Expect During the EOS Exam? 

 

  • You'll stand or sit inside an open, booth-like scanner 

  • It’s important to stay very still while the x-ray beam moves across the area being scanned 

  • The scan takes just 15-20 seconds 

 

What are the Benefits of an EOS Exam? 

EOS uses significantly less radiation than alternative imaging, making it a great option for children and those who need frequent imaging. The scan captures the body in its natural stance, giving doctors a clearer view of how your bones, joints, and spine align under normal conditions. This leads to more accurate diagnoses and better-informed treatment plans. 

 

What’s the Bottom Line? 

When it comes to your health, clear answers matter. EOS Imaging gives your care team a detailed view of your body—from head to toe—in just a few seconds.
