概括
超声波可以根据结节大小区分甲状腺髓性癌瘤 (MTCs) 和乳腺状甲状腺癌 (PTCs). 异常的血流信号是MTC中转移性淋巴结的诊断的关键,当超声波不确时,血清素 (CT) 有助于诊断.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 内分泌学 在内分泌学.
背景情况:
- 甲状腺髓性癌 (MTC) 和乳腺状甲状腺癌 (PTC) 是不同的甲状腺恶性瘤.
- 准确的手术前分化对于适当的治疗计划至关重要.
- 超声波是评估甲状腺结节的主要成像方法.
研究的目的:
- 为了研究超声波特征,在不同大小的结节中区分MTC和PTC.
- 确定用于区分MTC和PTC的关键超声波特征.
- 评估手术前血清标记在MTC诊断中的有用性.
主要方法:
- 追溯分析87个MTC和220个PTC病例的病理证实.
- 结节分为小 (≤1厘米) 和大 (>1厘米) 的分层.
- 在MTC和PTC之间比较超声波特征 (回声性,边缘性,血管性,化) 和转移性淋巴结检测.
- 在手术前分析血清素 (CT) 和癌胚抗原 (CEA) 水平.
主要成果:
- 与小型PTC相比,小型MTC更频繁地表现出低生理性,平滑边缘和血流信号 (P<0.05).
- 大型MTC比大型PTC更频繁地表现出囊性固体性,低可热性,平滑边缘,血液流动和IV型血管性 (P<0.05).
- 异常血流信号在MTC的转移性淋巴结 (82.1%) 中明显高于PTC (56.6%) (P=0.016).
- 转移性淋巴结的超声诊断合规性在大结节组中对MTC更高 (P=0.022).
结论:
- 用于区分MTC与PTC的超声波标准因结节大小而异.
- 异常的血流信号对于诊断转移性淋巴结在MTC中非常重要.
- 术前血清CT水平可以支持MTC诊断,当超声波特征是模两可的.

The Thyroid Gland
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...

Hyperthyroidism II: Pathophysiology
Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...
