概括

心脏计算机断层扫描 (CT-FD) 与心脏磁共振 (MR-FD) 显示出良好的一致性,用于评估左心室椎复杂性. 然而,在心缩期间严重的左心室缩的情况下,协议减少.

科学领域:

心脏病学心脏病学
医疗成像医学成像
生物物理学的生物物理.

背景情况:

评估左心室 (LV) 椎间板复杂性对于理解心脏功能至关重要.
分形维度 (FD) 分析提供了一种定量方法来评估这种复杂性.
评估不同成像方式之间的一致性对于临床应用至关重要.

研究的目的:

为了比较心脏计算机断层扫描 (CT-FD) 获得的碎形尺寸 (FD) 与心脏磁共振成像 (MR-FD) 获得的碎形尺寸.
为了评估CT-FD和MR-FD在评估左心室脊椎复杂性的一致性.
研究左心室缩 (LVH) 对CT-FD和MR-FD一致性的影响.

主要方法:

在两周内对170名接受CCT和CMR扫描的患者进行了回顾性分析.
选择五个短轴 cine 图像在终端透气 (基底,中,顶端切片).
重建和调整短轴CCT视图与CMR电影图像用于FD计算.

主要成果:

在透支CT-FD (1.253 ± 0.091) 和MR-FD (1.250 ± 0.102) (ICC = 0.882) 之间观察到高一致性.
在缩CT-FD (1.268 ± 0.072) 和MR-FD (1.286 ± 0.093) (ICC = 0.720) 之间发现了良好的一致性.
与非LVH (ICC = 0.773) 相比,在缩性LVH亚组 (ICC = 0.565) 中发现的一致性较低.

结论:

心脏计算机断层扫描 (CCT) 是一种可行的方法来评估左心室轨道肌复杂性.
CCT显示与心磁共振 (CMR) 对于FD分析有很好的一致性.
在缩期间严重的左心室缩时,协议减少,这表明在特定的临床情景中存在局限性.

Imaging Studies for Cardiovascular System V: CT

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...
