研究目的:

探索超分辨率(SR)重建多模态超声影像组学融合模型精准预测乳腺癌新辅助化疗(NAC)病理完全缓解(pCR)的价值及其分子生物学基础。次要目的:1. 评估超分辨率(SR)重建的增益效应:系统比较灰阶成像(GUS)、剪切波弹性成像(SWE)、平面波超微血管成像(AngioPLUS)在超分辨率重建前后深度学习影像组学模型(DLR)的预测性能差异,评估SR重建对模型效能的提升作用。2. 构建与优化多模态融合模型:基于SR重建的post-NAC多模态超声图像构建DLR,并整合患者baseline临床病理特征,探索影像–临床融合策略在提升乳腺癌新辅助化疗(NAC)疗效预测准确性中的作用。3. 评估模型的临床实用性与决策价值:通过受试者工作特征曲线(ROC)、决策曲线分析(DCA)及模型校准曲线等方法,系统评估影像–临床融合模型的预测稳定性与临床净获益,验证模型在NAC疗效评估中的可推广性和落地应用潜力。4. 探索模型的生物学基础:基于post-NAC关键影像组学特征,结合术后肿瘤组织样本的高通量测序数据开展影像–分子关联分析,从分子层面揭示影像特征所反映的肿瘤异质性及化疗敏感性机制,阐明模型预测的生物学依据。  

Objectives of Study:
