Abstract

This study was aimed to compare and analyze the magnetic resonance imaging (MRI) manifestations and surgical pathological results of endometrial cancer (EC) and to explore the clinical research of MRI in the diagnosis and staging of EC. . 80 patients with EC admitted to the hospital were selected as the research objects. The ResNet network was used to optimize the network. When the depth was added, the accuracy of the model was improved, the network parameters were iteratively updated, and the damage function of the minimized network was obtained. The recognition efficiency of MRI images was analyzed using three network modes: shallow CNN network, Res-Net network, and optimized network. The images of EC patients were analyzed, and a quantitative and timed MRI was achieved using simulated datasets in deep learning neural networks, which provided the basis for the formulation of single-scan MRI parameters. All patients underwent preoperative MRI examination using coronal and sagittal T1WI and T2WI imaging. The results showed that the accuracy and specificity of T2 weighted imaging and enhanced scanning in MRI were 88.75% and 95%, respectively. Sensitivity was 87.5%, negative predictive value was 93.75%, and positive predictive value was 86.25%. By MRI examination, 80 cases of EC in patients with stage I diagnosis were 72 cases, accounting for 90%, with endometrial thickening and uneven enhancement. In conclusion, the MRI manifestations of EC are diversified, and MRI has a high value for the staging of EC. MRI examination is conducive to improving diagnostic accuracy.

摘要

本研究旨在比较和分析子宫内膜癌(EC)的磁共振成像(MRI)表现和手术病理结果,并探讨 MRI 在 EC 诊断和分期中的临床研究价值。选取 80 例经医院确诊的 EC 患者作为研究对象。使用 ResNet 网络对网络进行优化。增加深度时,提高了模型的准确性,迭代更新网络参数,得到最小化网络的损伤函数。使用三种网络模式(浅 CNN 网络、Res-Net 网络和优化网络)分析 MRI 图像的识别效率。分析 EC 患者的图像,并在深度学习神经网络中使用模拟数据集实现定量和定时 MRI,为单扫描 MRI 参数的制定提供了依据。所有患者均采用冠状位和矢状位 T1WI 和 T2WI 成像进行术前 MRI 检查。结果表明,MRI 中 T2 加权成像和增强扫描的准确率和特异性分别为 88.75%和 95%,灵敏度为 87.5%,阴性预测值为 93.75%,阳性预测值为 86.25%。通过 MRI 检查,80 例 EC 患者中Ⅰ期诊断 72 例,占 90%,表现为子宫内膜增厚、不均匀强化。综上所述,EC 的 MRI 表现多样,MRI 对 EC 的分期具有较高的应用价值。MRI 检查有助于提高诊断准确性。
