评价用于阅读乳腺X线照片的交互式计算机辅助检测（CAD）系统，以改善决策。一个专门的乳腺摄影工作站已经开发出来，其中读者可以探测图像位置的CAD信息的存在。如果存在，则显示CAD结果以及计算的恶性等级。进行了一项读片员研究，其中四名筛选放射科医师和五名非放射科医师参与研究该系统对检测性能的影响。参与者阅读了120个病例，其中40个病例在最初的筛查中遗漏了恶性肿块。读片者在单独的会话中阅读每个有和没有CAD的乳房X线照片。每名阅片人报告了局部发现，并根据发现分配了恶性评分。在假阳性分数小于10%的区间内计算平均灵敏度。无CAD的平均敏感性为25.1%，CAD辅助的平均敏感性为34.8%。检测性能显着提高（p = 0.012）。在无辅助会话中，平均阅读时间为84.7 ± 61.5 s/例，使用交互式CAD时并不显著更长（85.9 ± 57.8 s/例）。在乳腺X线摄影中交互使用CAD可能比传统CAD更有效地改善肿块检测，而不会影响阅读时间。
To evaluate an interactive computer-aided detection (CAD) system for reading mammograms to improve decision making. A dedicated mammographic workstation has been developed in which readers can probe image locations for the presence of CAD information. If present, CAD findings are displayed with the computed malignancy rating. A reader study was conducted in which four screening radiologists and five non-radiologists participated to study the effect of this system on detection performance. The participants read 120 cases of which 40 cases had a malignant mass that was missed at the original screening. The readers read each mammogram both with and without CAD in separate sessions. Each reader reported localized findings and assigned a malignancy score per finding. Mean sensitivity was computed in an interval of false-positive fractions less than 10%. Mean sensitivity was 25.1% in the sessions without CAD and 34.8% in the CAD-assisted sessions. The increase in detection performance was significant (p = 0.012). Average reading time was 84.7 ± 61.5 s/case in the unaided sessions and was not significantly higher when interactive CAD was used (85.9 ± 57.8 s/case). Interactive use of CAD in mammography may be more effective than traditional CAD for improving mass detection without affecting reading time.
