研究目的: |
本研究旨在真实临床影像工作流中前瞻性静默运行已构建并锁定版本的人工智能模型,评价其在常规胸部非增强CT检查中对偶发性肺动脉栓塞的阳性提示质量、告警负担、潜在临床可操作性及系统运行稳定性。 |
||||||||||||||||||||||
|
Objectives of Study: |
This study aims to prospectively and silently run a built and version-locked artificial intelligence model within a real-world clinical imaging workflow, and to evaluate its performance in terms of the quality of positive alerts for incidental pulmonary embolism on routine non-contrast chest CT examinations, alert burden, potential clinical actionability, and system operational stability. |

纳入标准: |
1.年龄 ≥18 岁; 2.在研究期间内于参与中心完成常规胸部非增强CT检查; 3.经锁定版本人工智能模型判定为阳性 |

|
Inclusion criteria |
1.Age >=18 years. 2. Underwent a routine non-contrast chest CT examination at a participating center during the study period. 3. Judged as positive by the version?locked artificial intelligence model. |

|
排除标准: |
1.所纳入检查前已明确诊断肺动脉栓塞,且本次检查不属于新的机会性筛查场景; 2.该次检查以怀疑肺动脉栓塞为主要目的进行,或已明确进入肺动脉栓塞相关确证性检查路径; 3.基准检查影像存在严重运动伪影、金属伪影、数据损坏或扫描范围明显不足,无法进行可靠人工智能推理; 4.影像或临床资料严重缺失,无法完成基本核验流程。 |
||||||||||||||||||||||
|
Exclusion criteria: |
1. A definite diagnosis of pulmonary embolism was made prior to the enrolled examination, and the current examination does not represent a new opportunistic screening scenario. 2. The examination was performed primarily with suspected pulmonary embolism as the main purpose, or the patient had already been clearly entered into a confirmatory diagnostic pathway for pulmonary embolism. 3. The baseline examination images have severe motion artifacts, metal artifacts, data corruption, or clearly insufficient scan coverage, rendering reliable artificial intelligence inference impossible. 4. Severe lack of imaging or clinical data prevents completion of the basic verification process. |
