Positron Emission Tomography01:29

Positron Emission Tomography

5.9K
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...

科学领域:

  • 核医学就是核医学.
  • 医疗成像医学成像
  • 放射学 放射学是一门学科.

背景情况:

  • 基于深度学习的图像重建 (DLR) 算法已被开发用于PET/CT成像,以减少统计噪音.
  • DLR可能允许降低18F-FDG剂量,尽量减少辐射暴露,同时保持诊断质量.

研究的目的:

  • 评估DLR是否可以在PET/CT成像中减少注射的18F-FDG剂量.
  • 为了比较量化图像质量指标和低剂量DLR和标准剂量OSEM之间的错误阳性率.

主要方法:

  • 对90名接受18F-FDG PET/CT.的瘤病人的回顾性研究.
  • 患者被分为三个组:A组 (2.00-2.99 MBq/kg,DLR),B组 (3.00-3.99 MBq/kg,DLR) 和C组 (4.00-4.99 MBq/kg,OSEM).患者被分为两组.
  • 使用信号与噪声比率 (SNR),目标与背景比率 (TBR) 和假阳性率进行评估.

主要成果:

  • 与C组相比,DLR在A组和B组显著增加了SNR (p < 0.001).
  • 在DLR组 (A,B) 和OSEM组 (C) 之间,TBR没有显著差异.
  • 在B组,超过80%的<75kg的患者有≤1个假阳性;患者≥75kg和A组有≤80%的≤1个假阳性.

结论:

  • 注射的18F-FDG剂量可以降低到3.0MBq/kg,在75kg以下的患者中,DLR可以降低到3.0MBq/kg,比EANM指南减少36%.
  • 需要进一步优化DLR算法,以便在75kg以上的患者中获得可比的诊断准确性.
