目的：计算机辅助检测 (CAD) 提醒放射科医生注意可能与乳腺癌相关的发现，但因产生假阳性标记而臭名昭著。尽管之前的一篇论文发现放射科医生需要更多的时间来解释具有更多 CAD 标记的乳房 X 光照片，但我们的印象是，在实际解释中情况并非如此。我们假设，当这些标记数量较多时，放射科医生会选择性地忽略这些标记。方法：我们对双边数字筛查乳房 X 光检查进行了回顾性审查。我们使用混合线性回归模型来评估协变量调整后 CAD 标记数与 ln（解释时间）之间的关系。读数器和乳房 X 光检查均被视为随机抽样单位。结果：10 名放射科医生，平均经验为 12.5 年（范围 6 至 24）的住院医师经验，解读了 1832 个乳房 X 光检查。在考虑了图像数量、乳腺成像报告和数据系统类别以及乳腺密度后，CAD 标记的数量与较长的判读时间呈正相关，对于典型读者来说，每增加一个 CAD 标记，中位判读时间就会按比例增加 4.35%。 结论：我们的假设是，当 CAD 标记数量较多时，放射科医生会选择性地忽略它们，但我们的假设没有得到支持。
Purpose:Computer-aided detection (CAD) alerts radiologists to findings potentially associated with breast cancer but is notorious for creating false-positive marks. Although a previous paper found that radiologists took more time to interpret mammograms with more CAD marks, our impression was that this was not true in actual interpretation. We hypothesized that radiologists would selectively disregard these marks when present in larger numbers.Approach:We performed a retrospective review of bilateral digital screening mammograms. We use a mixed linear regression model to assess the relationship between number of CAD marks and ln (interpretation time) after adjustment for covariates. Both readers and mammograms were treated as random sampling units.Results:Ten radiologists, with median experience after residency of 12.5 years (range 6 to 24) interpreted 1832 mammograms. After accounting for number of images, Breast Imaging Reporting and Data System category, and breast density, the number of CAD marks was positively associated with longer interpretation time, with each additional CAD mark proportionally increasing median interpretation time by 4.35% for a typical reader.Conclusions:We found no support for our hypothesis that radiologists will selectively disregard CAD marks when they are present in larger numbers.
