This paper aims to explore the application value of SonoVue contrast-enhanced ultrasonography based on deep unsupervised learning (DNS) in the diagnosis of nipple discharge. In this paper, a new model (ODNS) is proposed based on the unsupervised learning model and stack self-coding network. The ultrasonic images of 1,725 patients with breast lesions in the shared database are used as the test data of the model. The differences in accuracy (Acc), recall (RE), sensitivity (Sen), and running time between the two models before and after optimization and other algorithms are compared. A total of 48 female patients with nipple discharge are enrolled. The differences in SE, specificity (SP), positive predictive value (PPV), and negative predictive value (NPV) of conventional ultrasound and contrast-enhanced ultrasonography are analyzed based on pathological examination results. The results showed that when the number of network layers is 5, the classification accuracies of DNS and ODNS model data reached the highest values, which were 91.45% and 98.64%, respectively.
本文旨在探讨基于深度无监督学习(DNS)的 SonoVue 超声造影在乳头溢液诊断中的应用价值。文中提出了一种新的模型(ODNS),它基于无监督学习模型和栈式自编码网络。该模型的测试数据来自共享数据库中 1725 例乳腺病变患者的超声图像。比较了两种模型及优化前后的其他算法的准确率(Acc)、召回率(RE)、灵敏度(Sen)和运行时间的差异。共纳入 48 例乳头溢液的女性患者,根据病理检查结果,分析了常规超声和超声造影的 SE、特异性(SP)、阳性预测值(PPV)和阴性预测值(NPV)的差异。结果表明,当网络层数为 5 时,DNS 和 ODNS 模型数据的分类准确率达到最高值,分别为 91.45%和 98.64%。
