Our purpose in this study was to examine the detectability of a lung nodule at different maximum luminance settings of a liquid-crystal display (LCD) monitor by utilizing receiver operating characteristic (ROC) analysis. The LCD monitor used in this study was calibrated to the grayscale standard display function with different maximum luminance settings (670, 450, and 170 cd/m(2)). The average area under the ROC curve (AUC) and the standard deviation for all observers at 670, 450, and 170 cd/m(2) were 0.837 +/- 0.076, 0.832 +/- 0.051, and 0.830 +/- 0.078, respectively. There was no statistically significant difference in AUC as a function of the maximum luminance setting of the LCD monitor. Considering the results, setting the maximum luminance of an LCD monitor at a higher level may not provide a significant advantage in the detectability of a lung nodule.
本研究的目的是通过利用接受者操作特征（ROC）分析，检测在液晶显示器（LCD）不同最大亮度设置下肺结节的可检测性。本研究中使用的LCD显示器根据不同的最大亮度设置（670、450和170 cd/m²）校准到灰度标准显示功能。在670、450和170 cd/m²时，所有观察者的ROC曲线下平均面积（AUC）和标准差分别为0.837±0.076、0.832±0.051和0.830±0.078。作为LCD显示器最大亮度设置的函数，AUC没有统计学上的显著差异。考虑到结果，将LCD显示器的最大亮度设置在较高水平可能在肺结节的可检测性方面没有显著优势。
