概括
对[18F]二氧化糖 (FDG) PET扫描的放射学分析可以预测软组织肉瘤 (STS) 的结果. 特定的放射性特征,如GLSZMSZNUN,显示出STS患者远程无复发和无疾病生存的显著预后价值.
科学领域:
- 在瘤学瘤学.
- 医疗成像医学成像
- 放射化学 放射化学是指辐射化学.
背景情况:
- 软组织肉瘤 (STS) 治疗依赖于阶段和临床病理因素.
- 放射学,FDG PET的定量图像分析,可以揭示 intratumoural代谢异质性.
- 关于放射学在预测STS结果中的实用性存在有限的数据.
研究的目的:
- 为了评估预治疗FDG PET衍生的放射性特征在STS患者的预后能力.
- 为了确定放射性特征是否可以改善复发和生存的预测.
- 评估放射学在标准临床因素之外的独立预后价值.
主要方法:
- 对44名STS患者进行了回顾性分析,这些患者接受了治疗的治疗意图.
- 使用40%的最高标准化吸收值值进行瘤细分.
- 提取了107个放射性特征,并使用单变量/多变量考克斯回归和卡普兰-梅尔曲线进行分析.
主要成果:
- 瘤异质性测量,特别是GLSZMSZNUN,显著预测了远程无复发存活率 (DRFS) 和无疾病存活率 (DFS).
- 多变量分析证实GLSZMSZNUN是DRFS和DFS的显著预测因子 (P<0.05).
- 来自ROC的值显示了局部无复发生存 (LRFS),DRFS和DFS (P <0.05) 的显著生存差异.
结论:
- 由FDG PET衍生出的放射性特征在STS中具有显著的预后效用,独立于临床因素.
- 这些特征可以预测软组织肉瘤的生存结果.
- 临床整合需要在更大的前性多中心研究中进一步验证.

Radiological Investigation III: Pulmonary Angiogram and PET Scan
387
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
6.8K
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...
