手持式超声波 (HAND) 设备为床边心脏评估提供了临床上可接受的准确性,包括左心室喷射率 (LVEF) 和中风体积 (SV) 的量化. 这些发现支持在血液动力学上受损的患者中使用它们.
科学领域:
- 心脏病学 心脏病学
- 医疗成像医学成像
- 临床诊断 临床诊断 临床诊断 临床诊断
背景情况:
- 床边对中风体积 (SV) 和左心室喷射率 (LVEF) 的量化对于管理血液动力学受损患者至关重要.
- 微型手持超声波 (HAND) 设备正在出现临床用途,但它们的性能对于定量心脏评估需要验证.
研究的目的:
- 为了将HAND设备的诊断有效性与标准心声回声 (SE) 和三维心声回声 (3DE) 进行比较,用于SV和LVEF量化.
- 评估HAND设备测量的图像质量和临床可接受性.
主要方法:
- 36名患者使用HAND,SE和3DE设备进行了心脏扫描.
- 从所有数据集中使用自动化软件来量化LVEF和SV.
- 使用分段内心边界划分得分来评估图像质量.
- 使用相关性和Bland-Altman分析来比较HAND测量与SE和3DE.
主要成果:
- HAND测量显示,LVEF (0.68) 和SV (0.91) 与SE的相关性很好,临床上可接受的偏差和一致性极限.
- 与3DE进行比较,发现HAND对LVEF量化具有可接受的准确性和精度.
- SE提供的图像质量得分明显优于HAND (P < 0.001).
结论:
- 与标准心声回声相比,手持式超声波设备在床边 LVEF 和 SV 量化方面显示出临床上可接受的准确性,精度和图像质量.
- 在重症监护机构中,HAND设备显示出对临床心脏评估的前景.

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...

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...
