概括

超声波减弱成像技术 (USAT) 显示了优秀的观察者间协议来评估肝脏脂肪含量,特别是在肋间间测量. 这种定量方法可靠地与视觉肥胖症分级相关.

科学领域:

肝病学肝病学是一种肝病学.
医疗成像医学成像
定量超声波检查是什么

背景情况:

与代谢功能障碍相关的脂肪性肝病 (MASLD) 是一个日益严重的健康问题.
准确量化肝脏脂肪含量对于诊断和管理至关重要.
目前用于肝肥胖症的视觉评估方法在可复制性方面存在限制.

研究的目的:

用超声波减弱成像技术 (USAT) 评估量化肝脂肪评估的观察者间变异性.
为了比较USAT测量与视觉分级的肝硬化.
在患有或疑似患有MASLD的患者中确定USAT的可复制性.

主要方法:

对96名怀疑患有MASLD的成年患者进行了前性单中心研究.
独立的,失明的观察员进行了视觉和USAT评估肝脏肥胖症.
在肋间间和肋下部位进行USAT测量,记录了中间值.
斯皮尔曼相关性,ICC和布兰德-阿尔特曼分析评估了USAT视觉相关性和观察者之间的变化.

主要成果:

对于USAT肋间测量进行的观测者间的良好协议 (p < 0.001).
对于USAT海岸下测量的良好观察者间协议 (p < 0.001).
USAT测量显示,与视觉肥胖症等级的相关性非常强 (p < 0.001).
观察者之间的变化在95%的协议范围内;BMI没有显著影响协议.

结论:

USAT提供可重复的肝脏脂肪含量的定量评估.
肋间间USAT测量表明肝硬化症的观察者间可再生性非常好.
USAT是一种可靠的工具,用于对肝脏脂肪的定量评估,与视觉分类有很好的相关性.

Ultrasonography

Ultrasonography

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.
During an ultrasonography procedure, a handheld device called...

Ultrasound I: Abdominal Ultrasonography

Ultrasound I: Abdominal Ultrasonography

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...
