Positron Emission Tomography01:29

Positron Emission Tomography

6.7K
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...

Imaging Studies II: Positron Emission Tomography and Scintigraphy

394
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Radiological Investigation III: Pulmonary Angiogram and PET Scan

325
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...

Area of Science:

  • Nuclear medicine
  • Radiology
  • Pediatric oncology

Background:

  • Fluorodeoxyglucose Positron Emission Tomography/Magnetic Resonance (FDG PET/MR) imaging is an emerging diagnostic tool.
  • Its application in pediatric oncology, particularly for lymphoma, is under investigation.
  • Current data is insufficient to establish its role in routine clinical practice.

Purpose of the Study:

  • To evaluate the current status and future potential of FDG PET/MR imaging in the staging and surveillance of pediatric lymphoma.
  • To identify the limitations and areas for further research in this field.

Main Methods:

  • Review of existing literature and current practices regarding FDG PET/MR imaging in pediatric lymphoma.
  • Analysis of protocol development, global availability, and cost-benefit considerations.

Main Results:

  • FDG PET/MR imaging protocols are still evolving.
  • Global availability of this technology is limited.
  • The cost-effectiveness and necessity for routine surveillance, especially compared to standard FDG PET, are not yet determined.

Conclusions:

  • FDG PET/MR imaging is not yet recommended for routine staging or surveillance in pediatric lymphoma due to insufficient data.
  • Further multicenter research is essential to define its optimal use in pediatric oncology.
  • Continued collaboration among institutions is crucial for advancing this technology.
