Study Design: Literature review.
Objective: The aim of this article is to introduce the EOS imaging device, with a focus on spinal and pelvic alignment.
Summary of Literature Review: The EOS imaging device can obtain images of spinal and pelvic alignment with almost no distortion, using a low radiation dose.
Materials and Methods: We searched for studies related to the use of EOS imaging device for spinal and pelvic alignment.
Results: The EOS is not only capable of simultaneously obtaining paired anteroposterior and lateral X-ray images with a low radiation dose, but also can reconstruct the image as if it was acquired in the patient's reference plane, limiting the distortion to the patient's thickness instead of the whole distance between the source and detector. The EOS device also has the advantage of accurately measuring the sagittal alignment of the spine and pelvis and the torsional deformity of the lower limbs, as the subject can be imaged while standing upright in a weight-bearing posture.
Conclusions: EOS is a new diagnostic technique that can detect spinal and pelvic alignment and deformities of the lower limbs under weight-bearing conditions with a low radiation dose.
