概括

来自18F-FDG PET/CT扫描的基于体积的生物标志物,特别是胸部和全身代谢体积 (MV),预测了沙丘症的进展. 标准化吸收值最大值 (SUVmax) 没有显示预后值.

科学领域:

核医学是一种核医学.
放射学放射学是一门学科.
肺部病理学肺部病理学

背景情况:

Sarcoidosis是一种复杂的多系统颗粒性疾病,临床表现各不相同.
由于其不可预测的性质和多样化的结果,管理类病是具有挑战性的.
18F-FDG PET/CT成像为评估疾病活动和预后提供了潜在的生物标志物.

研究的目的:

为了评估来自18F-FDG PET/CT的生物标志物的预后意义在患有沙尔科病的患者中.
为了确定代谢体积 (MV) 和标准化最大吸收值 (SUVmax) 是否可以预测疾病的进展.
识别基于成像的预测因子,以更好地临床管理沙尔科发病.

主要方法:

在诊断时,75名沙尔科病症患者接受了18F-FDG PET/CT.
疾病进展是由一个复合终点定义的,包括肺功能下降,图像恶化,症状或死亡.
胸部和全身代谢体积 (MV) 和SUVmax被计算为病变.

主要成果:

较高的基线胸部MV和全身MV与疾病进展有显著的关联.
为预测整体进展,MV胸部和MV全身的最佳值被确定为150厘米3.
无论是总SUVmax还是特定器官SUVmax都没有显示出与疾病进展结果的显著关联.

结论:

来自18F-FDG PET/CT的以体积为基础的生物标志物 (MV) 是肺沙丘病的有价值的预后指标.
来自18F-FDG PET/CT的SUVmax测量缺乏对型硬化症进展的预后影响.
这些发现表明,MV可能有助于风险分层和个人化治疗策略.

关键词:

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...
