Positron Emission Tomography01:29

Positron Emission Tomography

6.2K
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

722
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:

  • Oncology
  • Nuclear Medicine
  • Radiology

Background:

  • Lymphomas are diverse immune system cancers.
  • 18F-fludeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) is vital in Hodgkin's disease and aggressive non-Hodgkin's lymphoma management.
  • Its utility in indolent lymphomas requires further investigation.

Purpose of the Study:

  • To highlight the critical role of FDG PET/CT in lymphoma staging, prognostication, and treatment monitoring.
  • To emphasize the need for understanding diverse PET/CT findings for accurate diagnosis.
  • To discuss the limitations and optimal utilization of FDG PET/CT in lymphoma management.

Main Methods:

  • Review of current literature on FDG PET/CT applications in lymphoma.
  • Analysis of imaging findings and their diagnostic implications.
  • Evaluation of PET/CT's role across different lymphoma subtypes.

Main Results:

  • FDG PET/CT is the standard for staging and monitoring aggressive lymphomas.
  • It aids in prognostication, treatment planning, and recurrence detection.
  • The role of FDG PET/CT in indolent lymphomas remains to be fully elucidated.

Conclusions:

  • FDG PET/CT is indispensable for managing Hodgkin's and aggressive non-Hodgkin's lymphomas.
  • Familiarity with its varied manifestations and limitations is key for optimal use.
  • Further research is needed to define its role in indolent lymphoma subtypes.
