摘要:

主动筛查是全球范围内结核病防控的核心干预手段,胸部X线(chest radiography,CXR)为无症状人群筛查首选影像工具。当前,我国已构建 “被动因症就诊+社区主动筛查” 双轨并行的病例发现体系,在此基础上,行业共识进一步提出,推动胸部影像+人工智能计算机辅助检测(artificial intelligence-based computer-aided detection, AI-CAD)下沉基层并覆盖高危人群,是提升病例发现效率的核心路径。然而,现有研究多聚焦于AI模型的诊断效能验证,尚缺乏适配我国中低结核病流行背景的分层筛查标准、标准化全流程方案、系统的卫生经济学评价及覆盖的质量控制体系。依据世界卫生组织(World Health Organization,WHO)及我国现行结核病防控指南,本文首先系统梳理CXR在肺结核筛查中的政策定位,并分层划定适宜AI筛查的目标人群及分级影像设备配置要求;继而围绕“移动数字化X线摄影(digital radiography,DR)+AI”基层筛查模式,深入剖析人群适配性、流程设计、成本效益、模型泛化能力及质控体系五大落地瓶颈;最后,从标准化多源影像数据库建设、分层阶梯式筛查算法优化、一体化全流程质控机制构建、多病种联合筛查模式探索及本土化真实世界队列评估等5个维度,提出切实可行的优化策略。笔者旨在为构建“社区初筛-AI风险分流-病原学确诊-全程随访管理”的肺结核闭环防控体系提供系统性循证支撑。

Abstract:

Active case finding remains a cornerstone of global tuberculosis (TB) control, and chest radiography (CXR) is the primary imaging tool recommended for screening asymptomatic populations. In China, a dual-track case-finding system combining passive case finding among symptomatic individuals and communitybased active screening has been established. Building on this framework, expert consensus recommends the deployment of chest imaging combined with artificial intelligence-based computer-aided detection (AI-CAD) at primary care facilities, targeting highrisk groups to improve case-finding efficiency. However, existing studies have largely focused on validating the diagnostic performance of AI models, while critical gaps remain in the development of stratified screening standards tailored to China’s lowtomoderate TB burden setting, standardized endtoend workflows, systematic cost-effectiveness evaluations, and comprehensive quality assurance systems. Based on current World Health Organization (WHO) recommendations and national TB control guidelines, this commentary first clarifies the policy role of CXR in TB screening and proposes a stratified framework defining appropriate populations for AIassisted screening and tiered requirements for imaging equipment deployment. We then focus on the “mobile digital radiography (DR)-based screening combined with AI” model in primary care settings and analyze five major implementation challenges: population applicability, workflow optimization, costeffectiveness, model generalizability, and quality assurance. To address these challenges, we propose actionable strategies across five dimensions: (1)establishing standardized multisource imaging databases; (2)developing stratified and stepwise screening strategies and algorithms; (3)constructing integrated, end-to-end quality assurance mechanisms; (4)exploring multidisease integrated screening approaches; (5)conducting localized, realworld cohort evaluations. These efforts aim to provide systematic evidencebased support for establishing a closedloop TB prevention and control system integrating communitybased initial screening, AIdriven risk stratification, etiological confirmation, and longitudinal followup management.
