概括

对后部循环的间隔协议急性中风预后CT和CTA的早期计算机断层扫描得分 (pc-ASPECTS) 对于可重现的临床决定是不够的. 两体化并没有显著改善评级者之间的一致性.

科学领域:

神经辐射学神经辐射学
脑卒中成像脑卒中成像
临床评估临床评估

背景情况:

后部循环急性中风预后早期计算机断层扫描分数 (pc-ASPECTS) 是评估早期缺血变化的快速方法.
之前的研究缺乏对PC-ASPECTS的一致性分析.

研究的目的:

通过使用非对比CT (NCCT) 和CT血管学 (CTA) 源图像来评估pc-ASPECTS的interrater协议.
评估急性基底动脉封闭 (BAO) 的患者的同意.

主要方法:

潜在的急性BAO患者的招生 (2022年1月至2022年8月).
15名评级人员在两个会议期间独立评分了NCCT和CTA.
pc-ASPECTS在全尺度和二分化尺度上进行分析;通过Fleiss κ统计测量一致性.

主要成果:

基于CT (κ = 0.133) 和基于CTA (κ = 0.204) 的pc-ASPECTS之间的间隔协议很小.
异体化并没有显著增加间协议 (CT: κ = 0.350,CTA: κ = 0.396).
内部协议通常不够实质性,二分化后的改善有限.

结论:

对基于CT和基于CTA的pc-ASPECTS的临床医生一致意见对于可重现的临床决策是不够的.
双体化策略未能达到实质性的interrater或intrarater协议.

The Arch of Aorta

The Arch of Aorta

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.
Encircling the heart, the coronary arteries form a ring-like structure before...

Arteries of the Head and Neck

Arteries of the Head and Neck

The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.
The internal carotid arteries supply blood to the anterior portion of the cerebrum. They enter the...
