概括
剪切波弹性学 (SWE) 引导的超声波引导的细针吸收 (US-FNA) 显示了甲状腺结节的高精度. 然而,小结节,化和大型囊性成分增加了错误分类的风险.
科学领域:
- 放射学 放射学是指放射学
- 在瘤学瘤学.
- 病理学 病理学 病理学
背景情况:
- 超声引导细针吸收 (US-FNA) 对于评估甲状腺结节至关重要.
- 特定的超声波特征可能会影响US-FNA的充分性和准确性.
- 剪波弹性图 (SWE) 提供了针对性活检的定量刚性评估.
研究的目的:
- 评估用于甲状腺结节的SWE引导US-FNA的诊断准确性.
- 在US-FNA期间识别与错误分类相关的超声波特征.
主要方法:
- 从186名接受US-FNA的成年患者200个甲状腺结节的回顾性分析.
- 传统的超声波和SWE用于引导细针吸入到最硬的内区域.
- 手术组织病理学作为诊断的参考标准.
主要成果:
- 通过SWE引导的US-FNA实现了高诊断性能:灵敏度为92.5%,特异性为88.3%,准确度为90.0%.
- 卡帕统计 (κ = 0.81) 显示了与组织病理学的实质性一致.
- 直径小于10毫米的结节,内结节化和囊性成分>50%的结节独立地与诊断精度降低有关.
结论:
- 以SWE为指导的US-FNA显示出高诊断准确性和对甲状腺结节的组织病理学一致性.

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.
