概括
心声学与心磁共振 (CMR) 对儿科左心室喷射率 (LVEF) 的相关性很好,但倾向于高估LVEF和低估体积. 对于关键的临床决策,建议使用CMR.
科学领域:
- 儿科心脏病学 儿科心脏病学
- 心血管成像 - 心血管成像
- 心声回声扫描 (Echocardiography) 是一种心声回声扫描.
- 心脏磁力共振成像 (MRI)
背景情况:
- 准确量化儿科左心室 (LV) 体积和喷射分数 (EF) 是至关重要的,但缺乏共识方法.
- 心声谱被广泛使用,但与心磁共振 (CMR) 相比,它的准确性需要进一步调查.
研究的目的:
- 为了比较五六面积长度 (5/6 AL) 和修改的双平面辛普森 (BS) 声心谱方法与CMR对儿童的LV体积和EF评估.
- 评估儿科心血管成像中两种常见的回声心脏图像技术的准确性.
主要方法:
- 对儿科患者 (≤18岁) 的53项配对回声心电图和CMR研究的回顾性分析.
- 排除标准包括 >3个月间隔的研究,先天性心脏病或药物变化.
- 使用5/6AL和BS方法计算LV体积和EF,并与CMR测量进行比较,并进行子组分析.
主要成果:
- 5/6 AL和BS方法都与LVEF的CMR有很好的相关性 (分别r=0.85和r=0.82).
- 然而,与CMR相比,这两种心声回声方法都始终高估了LVEF,并低估了LV体积.
- 分析包括了对心肌炎和心肌病的研究.
结论:
- 与CMR相比,心声扫描为儿童的LVEF估计提供了良好的相关性.
- 心声测量倾向于低估LV体积和高估LVEF.
- 对于需要精确测量至关重要的临床决策的儿科患者,建议进行CMR成像.

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for...

Imaging Studies for Cardiovascular System I:Echocardiography
314
Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion,...

Imaging Studies for Cardiovascular System III: X-Ray
171
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...
