概括
人工智能检测乳腺动脉化 (BAC) 在乳房影像上,预测心血管疾病 (CVD) 风险. 这种人工智能增强的风险评估为妇女的预防性护理提供了宝贵的见解.
科学领域:
- 心脏病学 心脏病学
- 放射学 放射学是一门学科.
- 人工智能的人工智能
背景情况:
- 心血管疾病 (CVD) 在女性中被诊断不足和治疗不足.
- 乳房动脉化 (BAC) 在乳房扫描上可以表明心血管疾病风险.
- 目前的风险评估工具可能无法完全捕捉女性心血管疾病风险.
研究的目的:
- 评估基于人工智能的BAC自动量化从查乳房图片在预测心血管疾病和死亡率的有效性.
- 为了确定AI量化的BAC是否提供了超越现有的PREVENT分数的预后价值.
- 评估大量,多样化,多机构人口中的预测能力.
主要方法:
- 对123,762名接受了查性乳房造影的妇女进行了回顾性队列研究.
- 利用基于变压器的神经网络进行自动BAC量化.
- 采用卡普兰-梅尔分析,考克斯比例危险和细灰模型来评估BAC与主要不良心血管事件 (MACE) 的关联.
主要成果:
- 在16.1% (内部) 和20.6% (外部) 的女性中检测到BAC.
- 人工智能定量BAC显示了与PREVENT得分相比显著的预后值增量.
- 增加的BAC严重程度与更高的MACE风险相关 (例如,内部队列中严重的BACHR3.29).
- 每增加1毫米2的BAC都会增加2%-3%的MACE风险 (P<.001).
结论:

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...

Imaging Studies for Cardiovascular System III: X-Ray
560
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...
