Abstract

We evaluated the capabilities of a computed radiography system (CRS) and a standard radiography system (SRS) in the detection of simulated solitary pulmonary lung nodules of various sizes and contrast. A phantom simulated the pulmonary anatomy, and specially shaped plexiglass disks were externally mounted to simulate solitary pulmonary nodules of different diameters and thicknesses. ROC curves were generated based on the performance of each of the radiologists observing each film set. In this preliminary study, the overall performance for both the CRS and the SRS were comparable in detecting simulated pulmonary nodules.

摘要

我们评估了计算机X线摄影系统（CRS）和标准X线摄影系统（SRS）检测不同大小和对比度的模拟孤立性肺结节的能力。一个体模模拟肺部解剖结构，特殊形状的有机玻璃盘安装在外部以模拟不同直径和厚度的孤立性肺结节。根据每位放射科医生观察每组胶片的表现生成ROC曲线。在这项初步研究中，CRS和SRS在检测模拟肺结节方面的总体表现相当。
