The Effectiveness of Full-body EOS Compared With Conventional Chest X-ray in Preoperative Evaluation of the Chest for Patients Undergoing Spine Operations: A Preliminary Study

STUDY DESIGN.A prospective radiographic comparative study. OBJECTIVE.The aim of this study was to compare full-body EOS with conventional chest X-ray (CXR) for use in the preoperative evaluation of the chest in patients undergoing spine operations. SUMMARY OF BACKGROUND DATA.The full-body EOS reproduces an image of the chest similar to a routine CXR. The potential for the former replacing the latter is plausible. This is especially applicable in spine patients who would routinely have a preoperative full-body EOS performed. METHODS.A radiographic comparative study of 266 patients was conducted at a single tertiary center from January 2013 to July 2016. Each patient had EOS and CXR done in random order 18 years [odds ratio (OR) 7.69; P = 0.009] and American Society of Anesthesiologists physical status 3 (OR 6.64; P = 0.018) were independent predictors of abnormal radiological findings. CONCLUSION.EOS is not inferior to, and may be used to replace CXR in preoperative radiological screening of thoracic conditions especially in low-risk patients ≤18 years old and patients with ASA
