AbstractIn the last two decades, our military and federal health care facilities have transitioned from traditional X-rays exposing film screen systems, developed much like photographic film, to an entirely digital detection system that affords computer processing of images and digital image and report distribution. While health care providers are well aware of the practicality of these advancements, they may not be aware of the improved diagnostic capabilities afforded by these new methods. In this report, we outline how application of physical principles of X-rays, with digital detectors and computer data manipulation, can present images demonstrating chest and heart diseases that were previously not readily visible by traditional film screen systems. More recently, dual-energy, dual-exposure systems have been implemented. This commentary is to educate the medical community so that they may better understand not only the written report but the information on the images being provided, along with potential pitfalls to avoid. Specifically, we demonstrate improved detection of pulmonary nodules and coronary atherosclerosis with the dual-energy technique.Published by Oxford University Press on behalf of the Association of Military Surgeons of the United States 2022.
