概括
在PET/CT上偶发性弹性纤维瘤背部 (EFD) 显示稳定,低至中度的F-18 FDG吸收. 在正子发射断层扫描/计算机断层扫描上识别这些特征,可以防止对这种良性疾病进行不必要的干预.
科学领域:
- 瘤成像学成像学
- 核医学是一种核医学.
- 放射学 放射学是指放射学
背景情况:
- 弹性纤维瘤背部 (EFD) 是一种罕见的良性软组织瘤.
- 在F-18氧葡萄糖 (FDG) 定子发射断层扫描/计算机断层扫描 (PET/CT) 上偶然检测到EFD可以模仿恶性瘤.
- 了解EFD的成像特征对于癌症患者的准确诊断至关重要.
研究的目的:
- 评估F-18 FDG PET/CT.上偶然检测到的乳纤维瘤背部 (EFD) 的形态和代谢特征.
- 在3个月的随访期内评估瘤患者EFD的纵向变化.
主要方法:
- 从2019年1月到2023年9月,对42,197次PET/CT扫描进行了回顾性审查.
- 20个偶然发现的EFD病例的识别和分析.
- 记录病变的人口统计,恶性瘤类型,位置,尺寸和SUVmax;在治疗前和3个月后进行的测量.
主要成果:
- 在20名患者中偶然检测到EFD (0.05%),主要是女性 (85%),平均年龄为67.
- 在75%的病例中,病变是双边的,SUVmax的中位数为2.4 (右) 和2.5 (左),显示3个月的稳定吸收.
- 观察到左边最长直径的统计学上显著下降,这可能是由于测量的变化而不是生物变化.
结论:
- 在PET/CT上偶然检测到的EFD通常呈现出低至中等且稳定的FDG吸收.
- 主要双边局部化和特征性成像特征有助于区分EFD和恶性病变.
- 识别这些特征可以防止在瘤患者中进行不必要的诊断程序和干预.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
171
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...

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...
