概括
人工智能驱动的剪切波弹性图 (AI-SWE) 可以准确地检测乳腺癌, 这种人工智能工具显著减少了假阳性, 可能减少乳腺癌诊断中不必要的活检.
科学领域:
- 医学成像
- 医学的人工智能
- 癌症学
背景情况:
- 剪切波弹性图 (SWE) 显示为乳腺癌诊断中的B模式超声波的辅助.
- 由于乳腺成像报告和数据系统 (BI-RADS) 4的质量缺乏验证的速度值,因此SWE的采用有限.
- 深度学习 (DL) 模型为医疗成像数据的客观分析提供了潜力.
研究的目的:
- 开发和验证一个深度学习 (DL) 模型,称为AI-SWE,用于分析BI-RADS 3和4乳腺质量的SWE图像.
- 将AI-SWE的诊断性能与使用常规B模式超声波的人类专家进行比较.
主要方法:
- 使用来自7个国家的12个机构的国际多中心试验 (NCT02638935) 的数据.
- 使用来自11个地点的SWE图像开发了一个基于EfficientNetB1的DL模型.
- 使用最新的SWE软件对第12个站点和单独的机构队列的数据进行了外部验证.
主要成果:
- 在外部验证组中,AI-SWE实现了高诊断准确度,接收器操作者曲线下的面积 (AUROC) 为0.94和0.93.
- 与B模式超声波相比,AI-SWE显著降低了62. 1%和38. 1%的错误阳性率 (P < 0. 001).
- AI- SWE的灵敏度与人类专家相美 (97. 9%和97. 8%对比98. 1%,P=0. 912和P=0. 810).
结论:
- 在乳腺瘤检测中,AI-SWE的准确性与人类的解释相美.
- AI-SWE显著减少了错误的阳性结果,可能减少不必要的活检.
- 建议进一步研究将AI-SWE整合到多式乳腺癌诊断策略中.

Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
