The enhanced line and tube visibility and self-reported diagnostic confidence with dual-energy images underscore the clinical promise of portable dual-energy chest X-ray. Previous studies have also noted increased accuracy and interpretation speed for lung nodule identification with dual-energy subtraction [2]. Additionally, dual-energy X-ray imaging has been demonstrated to have a variety of clinical use cases beyond identification of lines, tubes, and pulmonary nodules, including identification of calcifications and vascular diseases, and bone, pleural, and chest wall abnormalities [3-5]. With single-exposure dual-energy X-ray detectors eliminating motion artefacts and reducing radiation doses, the potential for widespread adoption of dual-energy X-ray imaging has been re-opened. Consistent with previous findings, this study demonstrates improved clinical sensitivity and reader confidence with portable, single-exposure, dual-energy X-ray images [6]. Our study acknowledges limitations, including a small sample size and inclusion of only chest X-rays. The results may not be generalizable to imaging of other body parts and the diagnostic confidence outcome in this study used a subjective self-reported measure.

In summary, the integration of portable, single-exposure, dual-energy X-ray technology shows promise in enhancing line and tube visibility. This technology, compatible with existing equipment, offers opportunities to enhance chest X-ray capabilities across diverse clinical settings. Future research should explore its broader applications and potential impact on patient outcomes.
