摘要

目的：

探讨不同医师应用IOTA LR2模型对卵巢肿瘤良恶性评价的一致性。

方法：

回顾性分析876例卵巢肿瘤的超声图像，由两名不同年资医师在无临床及病理资料的情况下应用IOTA LR2模型对超声图像进行评价，将评价结果与病理学检查结果比较，判断其诊断效能，对两名医师的评价结果采用Kappa检验，判断一致性是否良好。

结果：

876例卵巢肿瘤中，病理诊断良性肿瘤837例，恶性肿瘤39例。应用LR2标准两名医师诊断的灵敏度、特异度分别为76.9%、67.0%及71.8%、76.0%，受试者工作特征（receiver operating characteristic，ROC）曲线的曲线下面积分别为0.8680.040、0.8470.043。两名医师诊断结果一致性良好，Kappa值为0.659（

0.01）。

结论：

应用IOTA LR2模型对卵巢肿瘤良恶性具有较高的诊断价值，且不同医师应用诊断的一致性良好。

Abstract

Objective:

To investigate the diagnostic consistency between physicians in differentiating malignant from benign ovarian tumors by using IOTA LR2 model.

Methods:

The ultrasonographic images of 876 ovarian tumors were retrospectively analyzed by two physicians with different seniorities in the absence of clinical and pathological data. The IOTA LR2 model was used to evaluate the ultrasonographic images. The results were compared with the pathological results to determine the diagnostic efficacy. Kappa test was used to determine the consisten

cy between two physicians.

Results:

Among 876 ovarian tumors

837 cases were benign and 39 were malignant. The sensitivity and specificity of the two physicians were 76.9%

67.0% and 71.8%

76.0%

respectively

and the area under the receiver operating characteristic (ROC) curve was 0.8680.040 and 0.8470.043

respectively. Kappa was 0.659 between the two physicians (

0.01).

Conclusion:

IOTA LR2 model has a high diagnostic value in differentiating malignant from benign ovarian tumors

and the diagnostic consistency between physicians is good.
