研究的目的:
- 评估一种全自动化深度学习 (DL) 方法的测试复制性,用于区域纵向应变 (RLS) 测量.
- 将DL衍生的RLS测量 (RLS领土和RLS水平) 与经验丰富的观察员使用的半自动方法的可复制性进行比较.
- 评估DL方法在临床应用中的可行性和效率.
主要方法:
- 使用了一组双中心测试复试数据集,包括40个对照组和40名患者.
- 每个受试者被不同的操作人员记录了两个连续的心声回声图.
- 区域纵向应变 (RLS) 使用新的DL点跟踪方法进行测量,并与三名经验丰富的观察员使用半自动软件 (EchoPAC) 进行比较. 使用最小可检测变化 (MDC) 和布兰德-阿尔特曼分析来评估可复制性.

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...

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,...
