概括
甲状腺结节的超声波评估显示,对于精细针吸收 (FNA) 决策,可以接受的协议. 然而,关于结节性特征和风险分层的医生间共识在分类系统中仍然有限.

- 内分泌学 在内分泌学.
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 超声波是甲状腺结节的主要成像方法.
- 操作员的解释导致了观察者之间的显著变化.
- 标准化分类系统的目的是减少变化.
研究的目的:
- 评估甲状腺结节特征的医生间协议.
- 通过多种分类系统评估风险分层的共识.
- 确定关于需要精细针吸收 (FNA) 的协议.
主要方法:
- 四位内分泌学家评估了100张甲状腺结节的超声波图像.
- 评估包括结节的组成,回声性,边缘和化.
- 用ATA,EU-TIRADS,K-TIRADS和ACR-TIRADS系统对结节进行了分类.
- 克里多夫的α被用来衡量观察者之间的协议.
主要成果:

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.

Synthesis and Regulation of Thyroid Hormones
4.6K
Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The...
