冠状动脉斑报告和数据系统 (RADS) 显示,经验丰富的读者在通过计算机断层扫描血管学 (CTA) 评估冠状动脉样硬化方面达成了大量的读者间一致. 对于初学者来说,有一个学习曲线,但随着经验的增加,一致性会提高,确保可重现的数据.
科学领域:
- 放射学 放射学是一门学科.
- 血管成像 血管成像
- 预防中风 预防中风
背景情况:
- 动脉狭窄是缺血性中风的主要原因.
- 斑块的组成和形态对于评估中风风险至关重要.
- 冠状动脉斑块报告和数据系统 (RADS) 标准化了超越狭窄度的斑块评估.
研究的目的:
- 为了评估 Carotid Plaque-RADS. 的读者间和读者内协议.
- 评估与状板-RADS实施相关的学习曲线.
- 为了在常规放射学实践中确定心血管斑块-RADS的可靠性.
主要方法:
- 追溯分析500个计算机断层扫描血管造影 (CTA) 检查 carotid 动脉样硬化.
- 三位具有不同经验水平的读者使用Carotid Plaque-RADS独立评估了动脉.
- 在多个评估块中使用科恩的kappa (κ) 计算的读者间和读者内部协议.
主要成果:
- 专家和中级阅读者之间存在实质上的共识 (κ=0.78-0.88).
- 在中级和初级阅读者之间,中等程度的一致性 (κ=0.50-0.74).
- 跨区块的专家-初学者协议显著改善,表明学习曲线.
- 对于中级和专家阅读器而言,几乎完美的读者内部协议 (κ=0.88).
结论:
- Carotid Plaque-RADS 在经验丰富和中级阅读者之间显示了实质性到近乎完美的读者间一致性.
- 对于初学者来说,学习曲线是显而易见的,随着时间的推移,协议得到了改进.
- 高的读者内部协议确保了分级的一致性和数据可重复性,用于心动脉板-RADS.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
