概括
静态超声图像显示,甲状腺结节风险分层系统 (RSS) 的观察者间协议 (IOA) 比视频序列 (cine-loops) 更好. 然而,观察员对RSS的经验显著减少了这种差异,突出了对甲状腺结节评估的专业知识的重要性.
科学领域:
- 放射学和成像学 放射学和成像学
- 医学诊断 医学诊断 医学诊断
- 超声波技术 超声波技术
背景情况:
- 甲状腺结节 (TNs) 需要准确的风险分层来进行适当的管理.
- 风险分层系统 (RSS) 用于基于超声波 (US) 特性对TNs进行分类.
- 观察者间协议 (IOA) 对TRN评估中RSS的可靠性至关重要.
研究的目的:
- 为了比较静态超声波图像与视频序列 (cine-loops) 对IOA对TN风险分层的影响.
- 为了评估不同的RSS如何使用静态图像和cine-loops的表现.
- 在TN评估中识别影响IOA的因素,使用US.
主要方法:
- 20个跨境网络由12名经验丰富的观察员使用5种不同的 RSS (Kwak-,ACR-,EU-,韩国-TIRADS,ATA指南) 进行评估.
- 观察员最初评估了美国的静态图像,然后,六个月后,使用cine-loops重新评估了相同的案例.
- 弗莱斯的卡帕 (κ) 用于测量静态和电影循环评估的IOA.
主要成果:
- 总的来说,IOA对于静态图像 (κ值在0.38-0.46之间) 与cine-loops (κ值在0.34-0.41之间) 相比更优越.
- 静态和电影循环之间的IOA差异在统计上是显著的 (p = 0.024).
- 观察者对RSS的体验显著影响了IOA,减少了静态图像的优势.
结论:
- 与多个RSS中的cine-loops相比,静态美国图像为TN风险分层提供了优越的IOA.
- 静态图像对电影循环的好处在经验丰富的观察者中不那么明显.
- 标准化美国特征和加强观察员培训是改善IOA在TN评估中的关键.

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...
