概括
评估乳腺动脉化 (BACs) 使用乳房扫描显示得分系统之间高度一致. 四级血管计数尺度为心血管风险评估提供了准确性和可重复性的实际平衡.
科学领域:
- 放射学 放射学是一门学科.
- 心血管成像 - 心血管成像
- 医学诊断 医学诊断 医学诊断
背景情况:
- 乳腺动脉结 (BAC) 在乳房影像上可见,可能表明心血管风险.
- 为了量化BACs,存在几种视觉评分系统,但它们的性能和临床实用性各不相同.
- 需要进一步研究BACs和冠状动脉化 (CACs) 之间的相关性.
研究的目的:
- 评估BAC五种不同的视觉评分系统的可复制性和诊断准确性.
- 评估这些系统评估的BAC与CAC之间的相关性.
- 为了确定每个BAC评分系统的临床适用性和效率.
主要方法:
- 对90名接受了乳房影像和心脏CT的女性进行了回顾性分析.
- 使用五种视觉系统对BAC进行评分:二分法,4级血管数,4级严重程度,4级综合和3级高级等级.
- 诊断性能 (灵敏度,特异性,AUC) 和观察者之间的一致性 (科恩的卡帕) 的评估;与CAC (阿加斯顿分数) 的相关性使用斯皮尔曼的rho.
主要成果:
- 在17.8%的女性中,BACs存在,并且显示出与CAC相关的趋势.
- 四级船舶计数量表显示,与CAC的相关性最强 (rho = 0.373;P <.001).
- 4级严重程度尺度产生了最高的AUC (0.604). 观察者间的一致性在各个系统中很高,特别是在4级综合尺度 (κ = 0.835) 中. 船舶计数尺度平衡了准确性,可重复性和效率.
结论:
- 在乳房镜上对BAC进行分级是可行的,只有观察者之间达成高度一致.
- 4级船舶计数尺度提供了准确性,可重复性和实用性的有利平衡.
- 这种尺度可能是基于乳房影像的心血管风险评估的宝贵工具.

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
545
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
502
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...

Imaging Studies for Cardiovascular System V: CT
400
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...
