Positron Emission Tomography01:29

Positron Emission Tomography

4.0K
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

86
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...

科学领域:

  • 在瘤学瘤学.
  • 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:

  • 一名75岁的女性患有头部和部转移性状细胞癌,呈现出右部质量.
  • 最初的成像表明,由于异常的18-氧葡萄糖 (18-FDG) 吸收模式,瘤的淋巴炎扩散.

研究的目的:

  • 在患有转移性头癌的患者中调查右质量和相关肺部异常的性质.
  • 使用先进的成像技术,区分淋巴炎扩散和肺部发现的其他潜在原因.

主要方法:

  • 用18-氧糖 (18-FDG) 的吸收评估进行的正子发射断层扫描-计算机断层扫描 (PET-CT).
  • 低剂量CT扫描用于肺细胞评估.
  • 光谱探测器CT (SDCT) 成像,以评估质量入侵和肺 perfusion.

主要成果:

  • 在右部/下部区域确定了一个质量,在右下叶中叶有扩散的18-FDG吸收.
  • SDCT证实该质量侵入了右下肺静脉.
  • 观察到右侧中侧和下侧肺叶的输液显著减少,这表明肺静脉封闭.

结论:

  • 这些发现导致了从怀疑的淋巴炎扩散到右肺静脉封闭的修订诊断.
  • 光谱探测器CT成像对于识别血管侵入和改变肺 perfusion 是至关重要的.
  • 这一案例凸显了先进成像在诊断转移性癌症复杂肺部表现方面的重要性.
