As the use of full-field digital screening mammography grows rapidly, this study was conducted to determine the time required to interpret digital soft-copy (filmless) mammography compared with conventional film-screen screening mammography and to evaluate radiologists' use of ancillary diagnostic aids when interpreting digital mammography (DM) and conventional film-screen mammography (FSM).
An 18-question survey was sent to 1,703 members of the Society of Breast Imaging, whose e-mail addresses were provided by the society. After subtracting those from whom out-of-office e-mail responses were received and three who wrote back to exclude themselves, there were 1,659 potential participants. Data from the respondents were collected and analyzed by tabulation and cross-tabulation.
In total, 396 members of the Society of Breast Imaging completed and returned surveys, for a 23.9% response rate. Of the respondents, 49.0% said that they had access to and interpreted DM. Their estimated average time to read a single digital mammographic study was 2.6 minutes, compared with 2.0 minutes for reading a single film-screen mammographic study. Therefore, the perceived time difference was 0.6 minutes. Magnification was the main ancillary diagnostic aid used in interpreting both DM and FSM: 74.2% of respondents used computer-based magnification at least half the time in interpreting DM, and 90.9% used optical magnification at least half the time in interpreting FSM. Optical magnification was also used by 28.5% of respondents at least half the time in interpreting DM. The respondents also used computer-aided detection frequently: 91.0% and 76.3% of those who had computer-aided detection available said that they used it at least 75% of the time in interpreting DM and FSM, respectively.
Digital mammography takes longer to interpret than FSM. Radiologists use various ancillary diagnostic aids, but magnification and computer-aided detection are the two most commonly used aids.
随着全视野数字化乳腺筛查钼靶摄影的使用迅速增加，开展本研究以确定解读数字化软拷贝（无胶片）乳腺钼靶摄影与传统屏-片乳腺筛查钼靶摄影所需的时间，并评估放射科医生在解读数字化乳腺钼靶摄影（DM）和传统屏-片乳腺钼靶摄影（FSM）时对辅助诊断工具的使用情况。
向1703名乳腺影像学会成员发送了一份包含18个问题的调查问卷，其电子邮件地址由该学会提供。在减去收到自动回复邮件的人员以及三名回复要求排除自己的数据后，有1659名潜在参与者。通过列表和交叉列表对受访者的数据进行收集和分析。
共有396名乳腺影像学会成员完成并返回了调查问卷，回复率为23.9%。在受访者中，49.0%表示他们能够获取并解读DM。他们估计解读一项数字化乳腺钼靶检查的平均时间为2.6分钟，而解读一项屏-片乳腺钼靶检查的平均时间为2.0分钟。因此，感知到的时间差异为0.6分钟。放大是解读DM和FSM时使用的主要辅助诊断工具：74.2%的受访者在解读DM时至少有一半时间使用基于计算机的放大功能，90.9%的受访者在解读FSM时至少有一半时间使用光学放大功能。28.5%的受访者在解读DM时至少有一半时间也使用光学放大功能。受访者也经常使用计算机辅助检测：在可使用计算机辅助检测的人员中，分别有91.0%和76.3%表示他们在解读DM和FSM时至少75%的时间会使用它。
解读数字化乳腺钼靶摄影比FSM花费的时间更长。放射科医生使用各种辅助诊断工具，但放大和计算机辅助检测是最常用的两种工具。
