概括
一个人工智能模型通过分析胸部X射线 (CXRs) 来自动化结核查,显著减少放射科医生的工作量并提高准确性. 这种人工智能放射学在查结核病 (AIRIS-TB) 模型实现了结核病检测0%的错误负率.
科学领域:
- 医疗成像中的人工智能
- 放射学和诊断成像 放射学和诊断成像
- 公共卫生和传染病控制
背景情况:
- 传统的结核病 (TB) 查依赖于放射科医生的手动胸部X射线 (CXR) 解释,这一过程是低效的,容易出现错误,并受到劳动力限制的压力.
- 对于全球卫生倡议来说,需要更快,更准确,更可扩展的结核病查方法至关重要.
研究的目的:
- 开发和评估一个人工智能 (AI) 模型,AIRIS-TB (AI Radiology In Screening TB),用于自动报告肺结核查中的正常胸部X射线 (CXR).
- 与人类放射科医生相比,评估AIRIS-TB在识别结核病和减少大量查环境中的工作负载方面的表现.
主要方法:
- AIRIS-TB人工智能模型是为了自动报告CXR而没有任何发现而开发的.
- 该模型的性能在超过100万个CXR的数据集上进行了评估.
- 关键的绩效指标包括曲线下面积 (AUC) 和假阴性率 (FNR),特别关注与结核病相关的FNR (TB-FNR).
主要成果:
- AIRIS-TB的AUC高达98.51%,整体FNR为1.57%,超过了放射科医生的平均FNR为1.85%.
- 最重要的是,AI模型保持了0%的TB-FNR,确保没有遗漏的TB病例.
- 该模型显示,通过将发现的病例推迟到放射科医生,可以将高达80%的常规CXR报告自动化.
结论:
- 大规模验证证实了AIRIS-TB在大量结核病查计划中的安全性和效率.
- AIRIS-TB有效地减少了放射科医生的工作量,而不会影响结核病检测的诊断准确性.
- 在不同的人口分组 (年龄,性别,艾滋病毒状况,地区) 中,表现保持一致,表明广泛适用.

207
Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...
