概括

[18F]化物 (Na[18F]F) -PET/CT成像显示在预测主要不良心血管事件 (MACE) 中具有前途. 大动脉中较高的Na[18F]F吸收与心血管风险增加相关,这表明其在风险分层中的有用性.

科学领域:

心血管成像 - 心血管成像
核医学就是核医学.
无线电学 (Radiomics) 是一种无线电学.

背景情况:

[18F]化物 (Na[18F]F) 定子发射断层扫描 (PET) 的目标是活性血管化,这是已知的心血管风险标志物.
以前的研究表明,Na[18F]F摄入量与心血管风险增加之间存在相关性.

研究的目的:

评估使用大动脉Na[18F]F-PET/CT作为主要心血管不良事件 (MACE) 风险预测模型的可行性.
评估大动脉化成像和MACE结果之间的相关性.

主要方法:

从2019年1月到2022年2月的Na[18F]F-PET/CT扫描的回顾性分析.
在低剂量CT上进行大动脉细分,并减去脊椎以最大限度地减少溢出.
总主动脉Na[18F]F校正的最大标准化吸收值 (cSUVmax) 和阿加斯顿分数的计算.
使用卡普兰-梅尔和考克斯回归的生存分析,按cSUVmax和Agatston得分类别分层.

主要成果:

在高和低cSUVmax组 (p=0.03和p<0.01) 之间观察到无MACE生存的显著差异.
与中低分数组相比,高Agatston分数患者的无MACE存活率明显较低 (p<0.01).
随访时间中位数为3.9年,记录了12个MACE事件.

结论:

大动脉Na[18F]F-PET/CT成像显示了预测MACE风险的工具的潜力.
这项概念验证研究需要进一步的临床验证,以确认其实用性并扩展其应用.

Imaging Studies for Cardiovascular System III: X-Ray

The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
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...
