概括
超声波弹性图学有效地区分良性与恶性甲状腺结节. 这种非侵入性技术,使用弹性图谱评分 (ES) 和应变比 (SR),显示出高精度,可以减少不必要的活检.
科学领域:
- 医疗成像医学成像
- 诊断性的超声波检查
- 在瘤学瘤学.
背景情况:
- 甲状腺结节很常见,区分良性和恶性是适当管理的关键.
- 目前的诊断方法,如细针吸收细胞学 (FNAC),可能是侵入性的,可能产生非诊断结果.
- 弹性图形提供了一种非侵入性的方法来评估组织硬度,这是恶性瘤的潜在指标.
研究的目的:
- 评估超声波弹性图 (ES和SR) 在区分良性和恶性甲状腺结节的诊断性能.
- 为了比较弹性图的准确性与组织病理学发现.
主要方法:
- 一项前性比较研究涉及来自44名患者的52个甲状腺结节.
- 经验丰富的超声波学家进行了弹性扫描,使用弹性扫描评分 (ES) 评估结节,并计算应变比 (SR).
- 确定ES和SR的诊断准确度 (灵敏度,特异性,PPV,NPV,准确度),并将其与最终的组织病理学结果进行比较.
主要成果:
- 弹性图谱评分 (ES) 显示,对良性结节的敏感度为88.9%,特异性为88.3%.
- 与恶性结节 (4.52 ± 0.75,P < 0.0001) 相比,良性结节 (2.72 ± 0.62) 的平均SR显着较低.
- 3.8的最佳SR切点产生了高诊断精度 (94.2%),灵敏度为88.9%,特异性为95.4%.
结论:
- 超声波弹性图 (ES和SR) 是区分良性和恶性甲状腺结节的一个有价值的工具.
- 弹性扫描显示出良好的诊断效果,可以作为传统灰度超声波的补充方法.
- 弹性图的使用可能有助于减少不必要的细针吸收活检的发生率.

Ultrasonography
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.

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...
