EOS orthopaedic imaging system is essentially which of the following?

• A. An ultrasound technique
• B. A CT with higher radiation
• C. Basically a CAT or PET scan but cuts the amount of radiation the patient is exposed to is greatly reduced
• D. A MRI plus X-ray

Answer: (C)

The key idea here is that EOS is a low-dose, biplanar X-ray system that captures full-body, standing orthopedic images and can generate 3D information about alignment. It provides CT-like spatial data, but with far less radiation than a conventional CT scan. That’s why describing EOS as basically a CAT or PET scan but with greatly reduced radiation fits best: it uses X-ray views from two perpendicular directions to reconstruct 3D information about the joints and bones, while keeping the radiation exposure much lower than typical CT or PET imaging. It’s not an ultrasound technique, not a CT with higher radiation, and not MRI plus X-ray.
