Methods and materials

A portable, single-exposure, dual-energy X-ray triple-layer detector (SpectralDRTM) was employed, allowing simultaneous acquisition of a conventional radiograph, a soft tissue image, and a bone image. Twenty-eight consecutive chest X-rays were obtained in an intensive care unit using the portable dual-energy detector, following institutional research ethics board approval and participant consent. Images underwent pre-processing to remove annotations and anonymize cases before distribution. A web-based survey-style review involving nine medical professionals and trainees with varying expertise levels was conducted, encompassing one medical student, four residents, one fellow, and three chest radiologists. Reviewers initially assessed cases using only the conventional radiograph, grading likelihood of pneumonia, pneumothorax, bone fractures, pulmonary nodules, and the visibility of lines and tubes on a 5-point scale. After a one-week washout period, reviewers re-evaluated cases using the same scale after reviewing additional soft tissue and bone images, with no clinical history provided. Reviewers reported presence of motion artefacts and indicated whether their diagnostic confidence increased with the additional dual-energy X-ray images, with review time recorded.
