概括
多样本点剪切波弹性学 (pSWE) 允许在一次呼吸中进行多达15次肝硬度测量,显示中等至高的相关性和与传统的pSWE技术的一致性.
科学领域:
- 医疗成像医学成像
- 肝病学 肝病学是一种肝病学.
- 超声波弹性成像 超声波弹性成像
背景情况:
- 肝硬度测量对于诊断和监测肝脏疾病至关重要.
- 传统的点剪波弹性图 (pSWE) 需要在几次呼吸中进行多次测量,这可能会增加获取时间和可变性.
研究的目的:
- 评估一项新型多样超声波点剪波弹性图形 (pSWE) 技术的技术性能.
- 这种技术使得在一次呼吸中可以获得多达15个单独的肝硬度测量.
主要方法:
- 56名超重和肥胖的成年人接受了使用传统PSWE和新的多样本PSWE技术的肝硬度测量.
- 传统的PSWE在五次呼吸中进行了五次测量,而多样本PSWE在一次呼吸中获得了多达15次测量.
- 测量结果在基线和重复会议后使用皮尔森相关系数和类内相关系数进行了比较.
主要成果:
- 使用不同的传感器 (r = .75-.88) 进行的传统pSWE测量和中等到良好的一致性 (ICC = .69-.81) 之间观察到很高的相关性.
- 多样 pSWE 与传统的 pSWE 显示了中度的相关性 (r = .59-.73) 和中度的一致性 (ICC = .58-.72).
- 用多样 pSWE 重复测量表明中等相关性 (r = .65) 和中等一致性 (ICC = .64).
结论:
- 多样本pSWE技术为肝硬度评估提供了一个有希望的替代方案.
- 与传统的pswe相比,它提供了中等到高的相关性和中等的协议,同时显著减少了获取时间.
- 这一进步可以提高效率,减少临床环境中的患者负担.

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
