However, critical patients are difficult to transport to the computed tomography suite. We previously reported a method to detect occult pneumothorax using oblique chest radiography (OXR). Several authors have also reported that ultrasonography is an effective technique for detecting occult pneumothorax. The aim of this study was to evaluate the usefulness of OXR in the diagnosis of the occult pneumothorax and to compare OXR with ultrasonography %K Oblique chest radiograph %K Lung ultrasound %K Occult pneumothorax %K Diagnosis %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4711032/
