This study explored the detectability of category 3 or higher microcalcifications using 5-MP color and monochrome monitors. Contrast detail mammography phantom with polymethyl methacrylate (PMMA) images were observed in color and monochrome by five radiographers, and the image quality figures (IQF) were calculated based on the gold disc locations identified. Five radiographers and two radiologists observed 200 mammograms from 100 patients (including 36 with microcalcifications) and rated the microcalcifications. The results were analyzed using area under the curve (AUC) and jackknife resampling. A paired t test was used for statistical analysis (p < 0.05). The mean IQF of color and monochrome monitors were 10.73 and 10.49 (30 mm PMMA, p = 0.653) and 8.47 and 8.74 (50 mm PMMA, p = 0.774), respectively. The mean AUC of color and monochrome monitors were 0.917 and 0.936 (p = 0.335), respectively, with windowing and magnification. The detectability of microcalcifications was not significantly different between the monitors.
本研究探讨了使用 5-MP 彩色和单色显示器检测 3 类或更高级别的微钙化的能力。使用 5 名放射技师分别在彩色和单色监视器上观察具有聚甲基丙烯酸甲酯 (PMMA) 图像的对比度细节乳房造影术体模，并根据识别的金盘位置计算图像质量因子 (IQF)。5 名放射技师和 2 名放射科医生观察了来自 100 名患者（包括 36 名有微钙化的患者）的 200 张乳房 X 光片，并对微钙化进行了评分。使用曲线下面积 (AUC) 和刀叉重采样进行结果分析（p < 0.05）。使用配对 t 检验进行统计学分析（p < 0.05）。彩色和单色监视器的平均 IQF 分别为 10.73 和 10.49（30mm PMMA，p = 0.653）和 8.47 和 8.74（50mm PMMA，p = 0.774）。彩色和单色监视器的平均 AUC 分别为 0.917 和 0.936（p = 0.335），均具有窗口和放大功能。在监视器之间，微钙化的检测能力没有显著差异。
