超声波弹性图的应用价值用于查怀孕早期的宫衰竭:一项追溯病例控制研究
1Department of Ultrasound in Medicine, Shanghai East Hospital, School of Medicine, Tongji University, Shanghai, China.
概括
测量宫应变率 (SR) 的宫弹性学是有效的查宫缺陷在怀孕早期. 宫内部开口的SR显示出与宫长度 (CL) 和子宫动脉血流相比更高的疗效.
科学领域:
- 产科和妇科 产科和妇科
- 医疗成像医学成像
- 生殖医学 生殖医学
背景情况:
- 宫功能不良会导致早产的风险.
- 早期检测和查对于治疗宫性衰竭至关重要.
- 目前的选方法可能在准确性上有局限性.
研究的目的:
- 在怀孕早期调查子宫张率 (SR),子宫长度 (CL) 和子宫动脉血流.
- 评估这些超声波参数的临床疗效,以查宫功能不充分.
主要方法:
- 对60名患有宫衰竭的妇女和100名正常怀孕的妇女进行了回顾性研究.
- 宫SR,CL和子宫动脉阻力指数 (RI) 的超声波测量在怀孕11-14周.
- 应变弹性学用于评估宫组织硬度.
主要成果:
- 宫缺陷组在内部和外部开口显著提高了SR (p < .001).
- 宫长度显著缩短 (p = .036) 和宫 perfusion 较差 (子宫动脉 RI,p = .048) 在不足组.
- 宫内部开口的SR显示出最高的诊断疗效 (AUC = 0.89,灵敏度78%,特异性82%).
结论:
- 宫弹性扫描是一种有效的工具,用于查怀孕早期的宫缺陷.
- 与CL和子宫动脉血流指数相比,在内部宫口的SR是查的有价值和优越的指标.

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.
