概括
多探测器计算机断层扫描 (MDCT) 和Technetium-99m放射标记的hydrazinonicotinylacid-d-phenylalanyl-tyrosine-octreotide (<99m>Tc-HYNIC-TOC) 能够有效地区分上腺瘤. 这些成像模式有助于精确诊断和表征上腺病变.
科学领域:
- 放射学 放射学是一门学科.
- 内分泌学 在内分泌学.
- 在瘤学瘤学.
背景情况:
- 主要上腺瘤 (AT) 存在由于功能异质性的各种临床表现.
- 准确地描述AT对于适当的患者管理至关重要.
研究的目的:
- 评估多探测器计算机断层扫描 (MDCT) 在特征上腺瘤方面的实用性.
- 评估Technetium-99m放射性标记的hydrazinonicotinylacid-d-phenylalanyl-tyrosine-octreotide (99mTc-HYNIC-TOC) 放射性核酸成像在诊断AT中的作用.
主要方法:
- 一项涉及50名已确诊的AT患者 (21名分泌激素,29名非功能) 的横截面研究.
- MDCT分析包括形态和动态评估 (定性,半定量,定量),计算绝对百分比冲洗 (APW) 和相对百分比冲洗 (RPW).
- 进行了Tc-HYNIC-TOC放射性核酸成像,并对标记物吸收进行了半定量分析.
主要成果:
- MDCT在检测上腺瘤的原生,静脉和延迟阶段中显示出统计学上显著的差异 (p < 0.05到p < 0.001).
- 延迟阶段,APW和RPW在区分功能上腺皮层病变方面是有效的 (p <0.05到p <0.001).
- Tc-HYNIC-TOC显示出高的诊断产量 (p < 0.001),在检测所有AT和上腺皮层腺瘤 (p < 0.01) 中,放射性核素成像和APW之间存在正相关性.
结论:
- MDCT和Tc-HYNIC-TOC放射性核酸成像是诊断上腺瘤的宝贵工具.
- 这些成像模式可以帮助精确诊断和表征,改善上腺病变的诊断算法.
- 了解每个模式的优点和局限性对于最佳的临床应用至关重要.

Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

2.2K
The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.

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.
