Which imaging modality reduces radiation exposure compared to standard CAT or PET scans?

• A. X-ray in limited field
• B. EOS orthopaedic imaging system
• C. MRI
• D. Ultrasound

Answer: (B)

Reducing radiation exposure is about getting the needed diagnostic information with the smallest dose of ionizing radiation possible. The EOS orthopaedic imaging system achieves this by using two synchronized X-ray beams taken from perpendicular directions (biplanar) to capture full-body or long-bone images in a way that requires much less radiation per exam than conventional CT or PET scans. Its detectors are highly efficient, and the system often delivers the necessary views in a single session with a lower dose, while still providing accurate measurements and 3D models through software reconstruction. While MRI and ultrasound avoid ionizing radiation altogether, EOS is designed to minimize radiation specifically for radiographic imaging in orthopedics, making it a standout choice when lowering radiation exposure compared with standard CT or PET scans.
