Dynamic chest radiography (DCR) is a flat‐panel detector (FPD)‐based functional lung imaging technique capable of measuring temporal changes in radiographic lung density due to ventilation and perfusion. The aim of this study was to determine the diagnostic performance of DCR in the evaluation of pulmonary function based on changes in radiographic lung density compared to nuclear medicine lung scans.

基于动态平板探测器的胸部放射线照相与核医学通气-灌注成像在评估肺功能方面的比较：一项临床验证研究。

动态胸部X射线摄影（DCR）是基于平板探测器（FPD）的功能性肺成像技术，能够测量由于通气和灌注引起的肺部X线密度的时间变化。这项研究的目的是根据与核医学肺部扫描相比射线照相肺密度的变化，确定DCR在评估肺功能中的诊断性能。
