A study conducted at the Hospital for Special Surgery in New York found the EOS imaging system uses less radiation and performs just as well as conventional CT scans in assessing limb length.
Here are four things to know:
1. Limb lengthening is a common condition frequently treated by pediatric and adult orthopedic surgeons.
2. The study was published in the Journal of Pediatric Orthopaedics.
3. Emily Dodwell, MD, a pediatric orthopedic surgeon at the Hospital for Special Surgery, said choosing an imaging modality to assess injury, deformity or alignment must balance the need for accurate measurements with the need to minimize radiation, a concept known as ALARA (as low as reasonably achievable.)
4. Study authors also noted that with EOS, a patient could in a standing, weight-bearing position, allowing for better assessment of limb alignment compared to CT in which the patient is lying down.
