研究目的:

当前针对疑似急性主动脉综合征(AAS)患者,缺乏一种简单且高效的早期诊断策略。本研究旨在于多中心前瞻性观察研究中,验证“AI辅助非增强CT结合ADDRS”在疑似AAS患者早期诊断中的有效性与安全性;并与现行ADDRS+D-二聚体策略比较诊断效能,得到高级别循证医学证据,形成快速、经济、可推广的标准化诊断路径,为减少漏诊与过度检查及优化指南提供循证依据。  

Objectives of Study:

At present, there is a lack of a simple and efficient early diagnostic strategy for patients with suspected acute aortic syndrome (AAS). This multicenter prospective observational study aims to validate the effectiveness and safety of an "AI-assisted non-contrast CT combined with ADD-RS" strategy for early diagnosis in patients with suspected AAS, and to compare its diagnostic performance with the current ADD-RS plus D-dimer strategy. By generating high-level evidence, the study seeks to establish a rapid, cost-effective, and scalable standardized diagnostic pathway, providing an evidence base to reduce missed diagnoses and unnecessary imaging and to inform future guideline optimization.
