概括
双平面高于宽 (TTW) 超声波标准为甲状腺结节恶性瘤诊断和精细针吸收 (FNA) 指导提供了卓越的准确性. 这一发现在中国 (C) -TIRADS和欧洲 (EU) -TIRADS框架内尤为重要,改善了风险分层.
科学领域:
- 放射学 放射学是一门学科.
- 在瘤学瘤学.
- 医疗成像医学成像
背景情况:
- 使用超声波 (美国) 评估甲状腺结节通常涉及评估高于宽 (TTW) 形状,但对此评估的最佳美国平面仍在争论中.
- 存在不同的甲状腺成像报告和数据系统 (TIRADS),每个都有特定的结节分类标准.
研究的目的:
- 为了比较各种TTW超声诊断标准的诊断性能,用于甲状腺结节恶性瘤预测.
- 在四个主要的TIRADS分类 (中国,美国,欧洲,韩国) 中确定最佳的TTW标准.
- 评估TTW标准在指导细针吸收 (FNA) 活检决策中的有用性.
主要方法:
- 从1125个甲状腺结节的手术前美国图像的回顾性审查.
- 定义了四个TTW标准:只有横平面 (T-only),只有纵平面 (L-only),两个平面 (双平面) 和一个或两个平面 (单平面或双平面).
- 评估诊断性能使用接收器操作特征曲线 (AUC) 下的面积和恶性瘤预测和FNA指导的净重新分类改进 (NRI).
主要成果:
- 单平面或双平面标准显示,当单独使用TTW时,恶性瘤的最高AUC (0.813) 是TTW.
- 在TIRADS中,双平面标准在中国 (C) -TIRADS (0.884) 和欧洲 (EU) -TIRADS (0.874) 中实现了最高的AUC.
- 双平面也证明了恶性瘤重新分类的改进,并在C-TIRADS和美国放射学学院 (ACR) -TIRADS中加强了FNA指导.
结论:
- 最佳的TTW超声波飞机选择取决于它是单独使用还是与其他可疑的美国特征一起使用.
- 在横向和纵向平面 (双平面) 中评估TTW形状为恶性瘤诊断和TIRADS内的FNA决策提供了更高的准确性.
- 这些发现为改进甲状腺结节评估指南和标准化活检建议提供了有价值的证据.

01:23The Thyroid Gland
8.1K
The thyroid gland is a small, butterfly-shaped gland located in the neck and covers the anterior surface of the trachea. The gland has two lateral lobes connected by a thin tissue mass called the isthmus. Internally, each lobe comprises many small spherical structures known as thyroid follicles, surrounded by a network of blood vessels.
The follicles have a central cavity lined by simple cuboidal to squamous epithelial cells called follicular cells. These cells produce the glycoprotein...

01:20Synthesis and Regulation of Thyroid Hormones
8.4K
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...

00:59The Parathyroid Glands
5.5K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Body planes in anatomy are imaginary flat surfaces used as reference points to divide the body into sections for anatomical study. These planes are essential for understanding the orientation, relationships, and spatial organization of anatomical structures.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

01:14Directional Terms
17.4K
Directional terms are essential for describing the relative locations of different body structures. For instance, an anatomist might describe one band of tissue as "inferior to" another, or a physician might describe a tumor as "superficial to" a deeper body structure. These terms often use comparative terms in pairs to trace out the relative locations of one body part to another or descriptions of body tissues like the deeper ones from superficially present with reference to...
