A clinical comparison study of scanning equalization radiography (SER) and conventional chest radiography was performed with the latest prototype SER system. Conventional chest radiography was performed at 120 kVp with Lanex regular screens (Eastman Kodak, Rochester, NY) and Kodak Ortho-G or Ortho-C film (Eastman Kodak). The 253 volunteer patients were examined with both techniques. The chest radiographs were interpreted by four radiologists. The study group was composed of 58 normal and 195 abnormal posteroanterior and lateral chest radiographs. In 31 cases there were two major radiologic diagnoses. The number of correct interpretations increased when the SER images were examined, compared with the conventional Ortho-G (chi 2 = 4.17, P less than .05) and conventional Ortho-C (chi 2 = 16.9, P less than .001) radiographs. The overall accuracy of disease detection improved for all radiologists with the SER system. There was no disease category in which the accuracy of interpretation decreased when the SER system was used. The SER system is a clinically reliable method of improving image quality and increasing diagnostic accuracy.
采用最新的扫描均衡射线照相术（SER）原型系统，对扫描均衡射线照相术（SER）和传统胸部射线照相术进行了临床比较研究。传统胸部射线照相术在120 kVp下进行，使用Lanex常规增感屏（伊士曼柯达公司，纽约罗切斯特）和柯达Ortho - G或Ortho - C胶片（伊士曼柯达公司）。对253名志愿者患者进行了两种技术的检查。胸部射线照片由四名放射科医生解读。研究组包括58例正常胸部后前位和侧位射线照片以及195例异常胸部后前位和侧位射线照片。在31例病例中有两种主要的放射学诊断。与传统的Ortho - G（χ² = 4.17，P < 0.05）和传统的Ortho - C（χ² = 16.9，P < 0.001）射线照片相比，当检查SER图像时，正确解读的数量增加。使用SER系统时，所有放射科医生对疾病检测的总体准确性均有所提高。使用SER系统时，没有任何疾病类别其解读准确性下降。SER系统是一种提高图像质量和增加诊断准确性的临床可靠方法。
