A clinical evaluation of one-shot dual-energy subtraction chest imaging by means of computed radiography (CR) with imaging plates was carried out in a comparison with the original plain CR images. In analyses of chest images of 140 patients, new information, not detected on the original plain CR images, was obtained on subtraction images in 21 patients (15%). Receiver operating characteristic curve studies also verified the superiority of CR subtraction over the original plain CR images for the detection of pulmonary nodules, calcification in a nodule, and rib lesions. Subtraction images complemented the original plain images.
通过使用成像板的计算机X线摄影（CR）对一次性双能减影胸部成像进行了临床评估，并与原始的普通CR图像进行了比较。在对140例患者的胸部图像分析中，21例患者（15%）的减影图像上获得了原始普通CR图像上未检测到的新信息。接受者操作特征曲线研究也证实了CR减影在检测肺结节、结节内钙化和肋骨病变方面优于原始普通CR图像。减影图像补充了原始普通图像。
