Radiological Investigation III: Pulmonary Angiogram and PET Scan

492
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 Tomography01:29

Positron Emission Tomography

7.7K
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...

Area of Science:

  • Oncology
  • Radiology
  • Medical Imaging

Background:

  • Radiation therapy (RT) is a cornerstone in lymphoma management.
  • Lymphomas are often metabolically active, readily accumulating 18F-fluorodeoxyglucose (FDG).
  • FDG-Positron Emission Tomography with Computed Tomography (PET/CT) is standard for staging and evaluating treatment response.

Purpose of the Study:

  • To highlight the role of FDG-PET/CT in modern radiation therapy for lymphoma.
  • To demonstrate how advanced imaging impacts radiation treatment planning.
  • To emphasize the benefits of integrating PET/CT with RT techniques.

Main Methods:

  • Utilizing FDG-PET/CT imaging for routine target delineation in RT planning.
  • Employing advanced imaging techniques such as image fusion and motion management.
  • Implementing highly conformal RT techniques.

Main Results:

  • FDG-PET/CT imaging significantly alters the irradiated volume compared to CT alone.
  • Integration of advanced imaging and RT techniques enhances treatment precision.
  • Improved precision allows for reduced long-term side effects.

Conclusions:

  • FDG-PET/CT is crucial for accurate RT contouring in lymphoma patients.
