概括

在PET/CT检测到的甲状腺意外瘤中,高二氧化糖 (FDG) 摄入量表明恶性瘤风险增加. 这一发现挑战了关于差异化良好的甲状腺癌显示低FDG吸收的先前假设.

科学领域:

核医学是一种核医学.
在瘤学瘤学.
放射学放射学是一门学科.

背景情况:

甲状腺附带瘤是FDG PET/CT的常见发现.
评估这些偶发性瘤的恶性瘤风险对于患者管理至关重要.

研究的目的:

调查FDG吸收模式与甲状腺意外瘤恶性瘤的可能性之间的相关性.
评估FDG PET/CT在区分良性与恶性甲状腺病变方面的诊断性能.

主要方法:

在FDG PET/CT.上对1611名患有甲状腺意外瘤的患者进行了回顾性分析.
组织病理学数据与FDG吸收模式 (扩散,焦点,混合) 和SUVmax值相关.
进行了统计分析,以比较良性和恶性群体之间的FDG摄入量.

主要成果:

在42%的患者中,SUVmax高于3.5.5的不确定的意义的恶性或无型性 (AUS) 发现.
与良性组 (2.2) 相比,恶性/AUS组 (5.3) 的中位数SUVmax显著高于良性组 (2.2) (p < 0.001).
在恶性小组中,乳头癌是最常见的恶性瘤 (61%).

结论:

甲状腺意外瘤中FDG吸收的增加与恶性瘤的风险增加有关.
FDG PET/CT可以有助于甲状腺附带瘤的风险分层,挑战了高度差异化的甲状腺癌吸收率低的观念.
值SUVmax为3.5可能有助于识别具有更高恶性潜力的甲状腺意外瘤.

Positron Emission Tomography

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Imaging Studies II: Positron Emission Tomography and Scintigraphy

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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...
