研究目的: |
主要目的:验证“基于胸部平扫CT联合人工智能的食管癌检测大模型”对于大规模真实世界人群的诊断准确性,评估其在真实世界机会性筛查中的阳性预测值(PPV)。 次要目的:在食管癌发病率低的中风险医院就诊人群中实现食管癌机会性发现,并探究该模型能否发现临床漏诊的食管癌。 |

Objectives of Study: |
Primary objective: To validate the diagnostic accuracy of a large model for esophageal cancer detection based on non‑contrast chest CT combined with artificial intelligence in a large real‑world population, and to evaluate its positive predictive value (PPV) in real‑world opportunistic screening. Secondary objective: To achieve opportunistic detection of esophageal cancer in a hospital‑visiting population with a low incidence of esophageal cancer (i.e., intermediate‑risk hospitals), and to investigate whether the model can identify clinically missed esophageal cancers. |
