概括
功能性/离散性发作概率评分 (FSLS) 帮助临床医生诊断功能性/离散性发作 (FDS),在三分之二的参与者中,诊断准确度提高了12-15%. 这个机器学习工具可以帮助临床医生更有效地识别FDS.
科学领域:
- 神经学 神经学
- 人工智能在医学中的应用
- 临床诊断 临床诊断 临床诊断
背景情况:
- 在没有视频脑电图的情况下诊断功能/离散性 (FDS) 是具有挑战性的.
- 功能性/离散性发作概率评分 (FSLS) 是一种机器学习工具,旨在帮助临床医生诊断FDS.
- 评估人类在循环中的FSLS实施对临床医生的诊断绩效对FDS与发作 (ES) 的影响至关重要.
研究的目的:
- 评估一个人-在-循环FSLS是否改善临床医师在区分FDS和ES的表现.
- 为了确定哪些临床医生群体从FSLS协助中获益最多.
主要方法:
- 使用了117个匿名的FDS,ES,同时发生的发作或生理事件的病例.
- 临床医生审查了基于文本的临床病史,其次是FSLS,并做出诊断决策.
- 混合模型和后勤回归被用来根据诊断性能模式对参与者进行分组.
主要成果:
- 163名读者评估了1142个案例,其中90%的表现高于机会.
- 接受了更多发作培训的临床医生表现出更高的准确性 (病学家67%,心理健康临床医生52%).
- 两组 (66%的读者) 在FSLS的帮助下显著提高了准确性 (12-15%),表明决策能力得到了增强.
结论:
- 虽然正式的发作训练与更好的FDS诊断相关,但不能保证高准确度.
- 对于66%的临床医生来说,FSLS有效地提高了决策能力,帮助他们调整诊断.
- 未来在FDS诊断中实现机器学习应该针对特定的临床场景,以最大限度地支持临床医生的决策.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
395
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...

Seizures: Classification
1.4K
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
