概括

该研究发现,18F-FDG PET/CT的SUVmax与CT最大瘤直径相比,是肺腺癌中通过空气空间 (STAS) 传播的优越预测指标. SUVmax为识别STAS提供了极好的特异性.

科学领域:

在瘤学瘤学.
放射学放射学是一门学科.
医疗成像医学成像

背景情况:

肺腺癌是癌症死亡的主要原因,需要准确的预后标志物.
通过空气空间传播 (STAS) 是肺腺癌中瘤侵略性行为的指标.
对于STAS,18F-FDG PET/CT与CT的比较预测值尚未得到充分证实.

研究的目的:

以回顾性分析手术前CT和18F-FDG PET/CT特征,用于预测肺腺癌中的STAS.
使用成像特征识别STAS的关键预测因素.
为了增强肺腺癌管理的临床决策.

主要方法:

分析了100名肺腺癌患者的108个病变.
患者接受了手术前的18F-FDG PET/CT,薄截面胸部CT和病理活检.
用单变量/多变量逻辑回归和ROC曲线分析来评估成像特征.

主要成果:

在60个病变中观察到STAS,其中偏向于主导的acinar模式.
无论是CT特征还是18F-FDG PET/CT特征都显示了STAS阳性和阴性病变之间的显著差异.
与最大瘤直径 (AUC 0.68) 相比,SUVmax (AUC 0.82) 是STAS的优越独立预测因子,显示出更高的灵敏度和特异性.

结论:

从18F-FDG PET/CT衍生出的SUVmax是预测肺腺癌中STAS的最佳成像模型.
放射性特征,特别是SUVmax,可以预测具有高特异性但中度灵敏度的STAS.

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...
