目的：本研究的目的是补充在乳腺筛查中应用三维 (3D) 乳房 X 线摄影的后勤方面的可用信息的匮乏。方法：通过比较二维 (2D) 乳房 X 线摄影与 2D+3D 乳房 X 线摄影相结合的图像采集时间和屏幕读取时间，前瞻性地研究了在筛查中实施 3D 乳房 X 线摄影对放射技师和放射科医师工作量的影响。还计算了放射科医生的准确性。结果：根据 20 次筛查检查，7 名放射技师的平均采集时间（从第一次查看乳房定位开始到最后一次查看完成时压缩释放），2D+3D（4 分钟 3 秒；范围 3 分钟 53 秒 - 4 分钟 18 秒）比 2D 乳房 X 光检查（3 分钟 13 秒；范围 3 分钟 0 秒 - 3 分钟 26 秒；范围 3 分钟 0 秒 - 3 分钟 26 秒；范围 3 分钟 53 秒 - 4 分钟 18 秒）更长。 p
Objective: The aim of this study was to supplement the paucity of information available on logistical aspects of the application of three-dimensional (3D) mammography in breast screening.Methods: We prospectively examined the effect on radiographers' and radiologists' workload of implementing 3D mammography in screening by comparing image acquisition time and screen-reading time for two-dimensional (2D) mammography with that of combined 2D+3D mammography. Radiologists' accuracy was also calculated.Results: Average acquisition time (measured from start of first-view breast positioning to compression release at completion of last view) for seven radiographers, based on 20 screening examinations, was longer for 2D+3D (4 min 3 s; range 3 min 53 s-4 min 18 s) than 2D mammography (3 min 13 s; range 3 min 0 s-3 min 26 s; p
