概括

亚急性甲状腺炎 (SAT) 可以呈现为来源不明的发烧 (FUO). 非对称的-18-二氧化葡萄糖正子发射断层扫描/计算机断层扫描 (18F-FDG PET/CT) 甲状腺吸收可能在FUO病例中表明SAT.

科学领域:

核医学是一种核医学.
内分泌学在内分泌学.
传染性疾病传染性疾病.

背景情况:

源不明的发烧 (FUO) 是一个诊断挑战.
亚急性甲状腺炎 (SAT) 是一种炎症性甲状腺疾病,通常与病毒感染有关.
像计算机断层扫描 (CT) 和血液检查等标准诊断方法可能无法确定FUO的原因.

研究的目的:

为了研究-18-氧糖素正子发射断层扫描/计算机断层扫描 (18F-FDG PET/CT) 在诊断亚急性甲状腺炎 (SAT) 在患有源不明发烧 (FUO) 的患者中的实用性.

主要方法:

一名48岁的男性患者患有持续发烧,接受了包括CT和血液检查在内的初步调查,但结果不确定.
患者接受了抗生素治疗,但没有改善.
进行了18F-FDG PET/CT,揭示了分散的,右叶主导的甲状腺吸收.
技术-99m基酸光学扫描显示,甲状腺的可视化不存在.

主要成果:

根据成像发现和临床表现,该患者被诊断为亚急性甲状腺炎 (SAT).
18F-FDG PET/CT证明了特征性的不对称的扩散性甲状腺吸收.
甲状腺扫描显示吸收受抑制,与SAT一致.

结论:

亚急性甲状腺炎 (SAT) 应在未知起源发烧 (FUO) 的差分诊断中考虑.
在PET/CT上,甲状腺中不对称的18F-FDG吸收可能是诊断FUO患者SAT的关键指标.
像18F-FDG PET/CT这样的先进成像可以帮助识别长期发烧的不常见原因.

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...

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...
