队列研究 

Study design:

Cohort study 

研究目的:

1. 探索直肠癌微环境异质性在功能学和形态学的表达机理,阐明 TDD-MRI 及深度组学动态解析直肠癌微环境时空异质性的可行性。 2. 阐明 NCRT 前后直肠癌 TDD-MRI 参数、深度影像组学特征的变化特性,及对 NCRT 疗效的影响规律。 3. 基于 TDD-MRI 与多模态影像深度组学,构建不同时点预测直肠癌 NCRT 疗效及并发症风险的多模态智能模型。  

Objectives of Study:

1. Explore the mechanisms of functional and morphological expression of rectal cancer microenvironment heterogeneity, and clarify the feasibility of using TDD-MRI and deep radiomics to dynamically analyze the spatiotemporal heterogeneity of the rectal cancer microenvironment. 2. Clarify the characteristics of changes in rectal cancer TDD-MRI parameters and deep imaging radiomic features before and after NCRT, and the patterns of their impact on NCRT efficacy. 3. Based on TDD-MRI and multimodal imaging deep radiomics, construct a multimodal intelligent model for predicting NCRT efficacy and risk of complications in rectal cancer at different time points.
