概括
与对比度增强的超声波 (CEUS) 环增强模式,特别是不规则的低环增强,在诊断甲状腺结节方面显示出高准确性. 与C-TIRADS相比,这种CEUS特性提高了特异性,特别是对于较大的结节,可能减少不必要的精细针的愿望.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 内分泌学 在内分泌学.
背景情况:
- 甲状腺结节很常见,需要准确地区分良性和恶性类型.
- 与对比度增强的超声波 (CEUS) 提供了详细的血管性评估,有助于结节的特征.
- 特定的CEUS模式,如环增强,可以提高诊断精度.
研究的目的:
- 评估CEUS环增强模式对甲状腺结节的诊断效率.
- 将CEUS功能与中国甲状腺成像报告和数据系统 (C-TIRADS) 的性能进行比较.
- 评估CEUS在鉴别良性与恶性甲状腺结节的有用性,考虑到结节的大小.
主要方法:
- 对302个甲状腺结节进行了回顾性分析,其中CEUS环增强 (135种良性,167种恶性).
- 环增强模式的分类为正规/不规则和超/低增强.
- 对US和CEUS特征的比较分析,以及CEUS模式与C-TIRADS的诊断性能.
主要成果:
- 不规则的低环增强在恶性结节中明显更频繁,被确定为独立预测因素.
- 具有不规则的低环增强标准的CEUS对所有结节的特异性比C-TIRADS (75.6%) 高 (85.2%).
- 对于≥10毫米的结节,CEUS特异性 (92.8%) 和AUC (0.907) 显著超过了C-TIRADS (81.1%,0.823).
结论:
- 在CEUS上不规则的低环增强是区分恶性甲状腺结节的一个有价值的特征.
- 与C-TIRADS相比,CEUS显示出更高的诊断特异性,特别是对于较大的结节 (≥10毫米).
- 使用不规则的缺氧环增强模式可能会减少不必要的细针吸收活检.

Ultrasonography
4.3K
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.

Nuclear Overhauser Enhancement (NOE)
641
Irradiation of a spin-active nucleus causes an increase or decrease in the signal intensity of neighboring nuclei that are not necessarily chemically bonded or involved in J-coupling. This phenomenon, called the Nuclear Overhauser Enhancement (NOE), results from through-space interactions between the nuclear spins. The NOE effect decreases with increasing internuclear distance and is generally not observed beyond 4 angstroms. In NOE, dipole-dipole interactions between neighboring...
