摘要:
目的:开发并验证基于多序列MRI的Swin Transformer(ST)深度学习模型在肝细胞癌(HCC)微血管侵犯(MVI)预测中的应用价值,为HCC患者的精准诊疗提供新的解决方案和客观、科学依据。方法:回顾性纳入徐州医科大学附属医院174例经手术病理确诊的HCC患者,收集患者的术前多序列MRI图像[动脉期(AP)、延迟期(DP)、脂肪抑制T2加权成像(T2WI-FS)、扩散加权成像(DWI)],经过图像预处理和增强后,构建基于ST的DL模型,并将其与基于卷积神经网络(CNN)架构的DenseNet121、DenseNet169、ResNet34、ResNet50、VGG16、GoogleNet模型,基于Transformer架构的Vision Transformer(ViT)模型以及影像组学模型进行对比,计算模型的准确率、受试者工作特征曲线下面积(AUC)、敏感度、特异度,通过混淆矩阵和决策曲线分析(DCA)评估性能。为提高模型的可解释,采用梯度加权类激活映射(Grad-CAM)可视化模型关注区域。结果:ST模型在4个序列的MVI预测任务中总体性能最好,特别是DP序列上预测结果最优,其准确度、AUC(95%CI)、敏感度和特异度分别为0.944、0.993(0.985~0.998)、0.984和0.904,显著优于其他深度学习模型和影像组学模型,DCA图进一步证实其卓越的临床应用价值。Grad-CAM结果显示ST模型能够有效关注肿瘤相关区域。结论:ST在不同序列MRI图像上的各项指标均表现出优异的预测性能,可为临床诊断、治疗决策及预后评估提供有力的辅助工具。
Abstract:
Abstract: Objective To develop and validate a Swin Transformer (ST)-based deep learning (DL) model using multi-sequence magnetic resonance imaging (MRI) for predicting microvascular invasion (MVI) in hepatocellular carcinoma (HCC), thereby providing a novel solution and objective scientific evidence to facilitate the precision diagnosis and treatment for HCC patients. Methods A retrospective analysis was performed on 174 patients with surgically and pathologically confirmed HCC who were admitted to the Affiliated Hospital of Xuzhou Medical University. Preoperative multi-sequence MRI images, including arterial phase, delayed phase (DP), fat-suppressed T2-weighted imaging, and diffusion-weighted imaging, were collected for each patient. After image preprocessing and enhancement, an ST-based DL model was established and then compared with models based on convolutional neural network architectures, including DenseNet121, DenseNet169, ResNet34, ResNet50, VGG16, and GoogleNet, as well as a Transformer-based Vision Transformer model and a radiomics model. Model accuracy, area under the receiver operating characteristic curve (AUC), sensitivity, and specificity were calculated, and the model performance was evaluated using confusion matrices and decision curve analysis. To enhance model interpretability, gradient-weighted class activation mapping (Grad-CAM) was employed to visualize the regions of interest focused on by the models. Results The ST model demonstrated the optimal overall performance among the 4 sequences in MVI prediction, with particularly outstanding results on the DP sequence. Specifically, it achieved an accuracy of 0.944, an AUC of 0.993 (95% CI: 0.985-0.998), a sensitivity of 0.984, and a specificity of 0.904, significantly outperforming other DL models and the radiomics model. Decision curve analysis further confirmed its superior potential for clinical application. Grad-CAM visualization indicated that the ST model effectively concentrated on tumor-associated regions. Conclusion The ST model exhibits excellent predictive performance across multiple MRI sequences and can served as a powerful auxiliary tool to support clinical diagnosis, treatment decision-making, and prognostic evaluation.
