如何引用文章
详细
理由: 医学图像集的标记在很大程度上依赖于观察到的可疑结构的主观解释。目前,没有推荐的协议用于根据医学描述确定参考数据(ground truth)。
目标: 评估参与编制公开数据集»CTLungCa-500»的放射科医生评估的正确性和一致性,以及确定这些指标与对CT研究进行独立解释的专家数量的关系。
方法: 该数据集包括有患肺癌风险的患者的536项CT研究,其中34名放射科医生参加了该研究。每项CT研究都由六位专家独立解释,之后他们发现的可疑结构由另一位专家进行仲裁。对于每位专家计算真阳性,假阳性,真阴性和假阴性结果的数量,在此基础上评估放射科医生的诊断准确性。为了分析放射科医生的结论之间的一致性,使用了百分比度量。
结果:对CT研究进行独立解释的专家数量的增加在一致性降低的情况下导致其评估的正确性增加。在影响成对研究人员之间结论一致性的因素中,关于CT图像的特定部分中存在肺焦点的观点不一致。
结论:独立的初级解释数量的增加使它们的组合正确性会升高,但需要仲裁,放射科医生的资格对分析的质量没有决定性的价值。从结合解释的正确性及其成本的角度来看,由四名放射科医生进行主要标记是最佳的。
