研究目的: |
本项目旨在通过多中心回顾性分析与前瞻性验证相结合的研究设计,构建并验证一套基于肺动脉CTA影像组学与多模态数据的智能风险预测体系。具体目标为:首先,利用卷积网络、注意力机制等深度学习技术,融合肺动脉CTA影像组学特征及临床、超声等多源数据,从血管、血栓、心肺解剖与功能等多维度构建能够早期识别非高危急性肺栓塞患者“恶化倾向”的智能评估模型;其次,通过独立的多中心前瞻性队列对该模型进行外部验证,系统评估其预测效能,并将其与传统肺栓塞严重程度评分(PESI/sPESI)进行优劣比较,最终形成一种能够快速、准确识别非高危肺栓塞恶化风险的临床预测工具,以辅助临床决策、改善患者预后。 |

Objectives of Study: |
This project aims to develop and validate an intelligent risk prediction system based on pulmonary artery CTA radiomics and multimodal data through a multicenter retrospective analysis and prospective validation study design. The specific objectives are: first, to utilize deep learning technologies such as convolutional networks and attention mechanisms, integrating pulmonary artery CTA radiomics features with multi-source data including clinical and ultrasound information, to construct an intelligent assessment model capable of early identification of "deterioration tendency" in non-high-risk acute pulmonary embolism patients from multiple dimensions such as vascular, thrombus, cardiopulmonary anatomy, and function; second, to externally validate this model through an independent multicenter prospective cohort, systematically evaluate its predictive performance, and compare its advantages and disadvantages with traditional pulmonary embolism severity scores (PESI/sPESI), ultimately forming a clinical prediction tool that can rapidly and accurately identify the risk of deterioration in non-high-risk pulmonary embolism to support clinical decision-making and improve patient outcomes. |
