概括
针对自主功能甲状腺结节 (AFTN) 的放射性治疗 (RAIT) 可能会导致结节扩大或持续性甲状腺功能障碍. 治疗前的结节体积预测了这些结果,随着时间的推移,RAIT后的体积会减少.
科学领域:
- 内分泌学 在内分泌学.
- 核医学就是核医学.
- 在瘤学瘤学.
背景情况:
- 自主功能甲状腺结节 (AFTN) 是甲状腺功能过高的常见原因.
- 放射性治疗 (RAIT) 是AFTN的标准治疗方法.
- 关于结节体积和甲状腺功能RAIT的长期结果需要进一步调查.
研究的目的:
- 调查500MBq剂量RAIT与甲状腺结节体积和甲状腺功能变化在AFTN患者之间的关联.
- 在RAIT后识别结核扩大和持续性甲状腺功能障碍的危险因素.
- 为提供单次固定剂量RAIT后结节体积变化和甲状腺功能的长期结果数据.
主要方法:
- 对201名AFTN患者进行了回顾性研究,这些患者接受了500MBqRAIT治疗.
- 随访持续时间超过2年.
- 评估甲状腺功能,抗体阳性,RAIT前使用抗甲状腺药物,结节囊性成分和131I吸收.
主要成果:
- 结节扩大发生在9%的患者中,持续性甲状腺功能障碍发生在6.5%,甲状腺功能障碍发生在22.3%中.
- 较大的RAIT前结节体积与结节体扩大和持续性甲状腺功能障碍有关.
- 确定了预测扩大 (15.5毫升) 和持续性甲状腺功能障碍 (16.6毫升) 的切断体积.
- 在RAIT后的第一年,结节体积下降了47%,并继续逐渐下降.
结论:
- 治疗前的结节体积是AFTNRAIT后结节体扩大和持续性甲状腺功能障碍的重要预测因素.
- 一次500MBq的RAIT剂量会随着时间的推移导致结节体积的逐渐减少.
- 了解风险因素和预测结果对于优化AFTN管理中的RAIT至关重要.

Synthesis and Regulation of Thyroid Hormones
4.2K
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...

Radiological Investigation III: Pulmonary Angiogram and PET Scan
82
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
