Dynamic chest radiography (DCR) is a real-time sequential high-resolution digital X-ray imaging system of the thorax in motion over the respiratory cycle, utilising pulsed image exposure and a larger field of view than fluoroscopy coupled with a low radiation dose, where post-acquisition image processing by computer algorithm automatically characterises the motion of thoracic structures. We conducted a systematic review of the literature and found 29 relevant publications describing its use in humans including the assessment of diaphragm and chest wall motion, measurement of pulmonary ventilation and perfusion, and the assessment of airway narrowing. Work is ongoing in several other areas including assessment of diaphragmatic paralysis. We assess the findings, methodology and limitations of DCR, and we discuss the current and future roles of this promising medical imaging technology.Critical relevance statement Dynamic chest radiography provides a wealth of clinical information, but further research is required to identify its clinical niche.
动态胸部X线摄影（DCR）是一种实时连续的高分辨率数字X线成像系统，用于在呼吸周期中对运动的胸部进行成像，它利用脉冲图像曝光，视野比荧光透视更大，辐射剂量低，通过计算机算法进行采集后图像处理可自动表征胸部结构的运动。我们对文献进行了系统综述，发现有29篇相关出版物描述了其在人体中的应用，包括评估膈肌和胸壁运动、测量肺通气和灌注以及评估气道狭窄。其他几个领域的研究也在进行中，包括评估膈肌麻痹。我们评估了DCR的研究结果、方法和局限性，并讨论了这种有前景的医学成像技术的当前和未来作用。关键相关性声明：动态胸部X线摄影提供了丰富的临床信息，但需要进一步研究以确定其临床应用领域。
