胸部X射线 (CXR) 上的肺外发现的临床注释在经验水平上都是可靠的. 一个标准化的标签方案确保了一致的解释,有助于临床决策和AI模型培训.
科学领域:
- 放射学 放射学是一门学科.
- 医学成像分析 医学成像分析
- 临床决策支持 临床决策支持
背景情况:
- 对胸部X射线 (CXR) 的准确解释对于患者护理和人工智能 (AI) 发展至关重要.
- 现有的研究主要集中在肺部发现上,对肺外异常的关注较少.
- 评估肺外发现注释的一致性对于可靠的诊断过程至关重要.
研究的目的:
- 评估临床医生对CXR肺外发现的注释的可靠性和一致性.
- 为了比较不同临床医生经验水平 (新手,中级,经验丰富) 的注释协议.
- 评估标准化诊断标签方案对注释一致性的影响.
主要方法:
- 六位临床医生用诊断标记方案在两轮检查中注释了100个CXR用于肺外发现.
- 使用兰道夫卡帕 (RK),PABAK,PPA和PNA来测量注释一致性.
- 通过对对比和麦克纳马的测试,分析了读者间和读者内部的协议.
主要成果:
- 在所有经验水平 (0.86-0.91) 中观察到高整体分组标签协议 (PABAK).
- 对负面发现 (PNA) 发现了强烈的一致性,而积极的发现显示了中等至低的一致性 (PPA).
- 经验水平之间没有发现RK的显著差异,并且在各轮之间确认了注释稳定性.
结论:
- 当使用定义的诊断标签方案时,临床人员对肺外CXR发现的注释是一致的和可靠的.
- 这些发现支持使用标准化方案来提高诊断准确性和人工智能模型培训.
- 这项研究为放射学中人类口译员和人工智能系统的优化培训策略提供了见解.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
