概括
声波辐射力冲动 (ARFI) 弹性成像是可行的评估脏病变,显示较低的硬度比正常的脏外围膜. 然而,这种方法无法区分良性和恶性焦点脏病变.
科学领域:
- 放射学 放射学是一门学科.
- 医疗成像医学成像
- 超声波技术 超声波技术 超声波技术
背景情况:
- 非创伤性焦点病变 (FSL) 是罕见的,并带来组织活检出血的风险.
- 声波辐射力脉冲 (ARFI) 弹性图形提供了一种非侵入性的方法来评估组织硬度.
研究的目的:
- 评估ARFI弹性图的可行性和诊断潜力,以区分良性和恶性焦点脏病变.
- 为了研究FSL在人类中的弹性特征,因为没有先前的研究存在.
主要方法:
- 对34名FSL患者进行了B模式超声波,对比度增强超声波 (CEUS) 和ARFI检查的回顾性分析.
- 对FSL的ARFI测量和正常的膜膜 (NSP) 进行了比较.
- 通过组织学或临床/成像随访证实了FSL病因.
主要成果:
- 对于所有FSL来说,ARFI弹性学是可行的,病变刚度 (MAVL) 低于NSP刚度 (MAVP) (p=0.009).
- 在恶性和良性FSL之间没有发现MAVL,MAVP或MAVL/P比的显著差异.
- 所有FSL的平均MAVL/P比为0.90±0.34.所有FSL的平均MAVL/P比为0.90±0.34.
结论:
- ARFI弹性成像是一种可行的技术,用于评估脏病变的度.
- 损伤的度始终低于正常的干膜,不论病因.
- 目前的ARFI弹性图形无法区分良性和恶性FSL.

4.5K
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.

01:18Assessment of the Abdomen II: Percussion
363
Percussion is a fundamental technique used to assess the liver, spleen, and abdominal organs by tapping the abdomen and interpreting the resulting sounds. This method helps identify fluid, distention, and masses through variations in sound, such as the high-pitched tympany of air-filled areas and the dullness of solid masses. Understanding how to percuss these organs provides valuable information for healthcare professionals in diagnosing conditions early.
