International journal of radiation oncology, biology, physics·2026

Integrated PET/CT imaging, particularly with 18F-fluorodeoxyglucose (FDG), enhances diagnostic performance in oncologic imaging. This technology improves confidence and accuracy compared to standalone methods, with future potential for new radiopharmaceuticals and bone imaging.

Area of Science:

  • Nuclear Medicine
  • Radiology
  • Oncologic Imaging

Background:

  • Positron Emission Tomography/Computed Tomography (PET/CT) has significantly accelerated PET adoption globally.
  • Oncologic imaging, primarily using 18F-fluorodeoxyglucose (FDG), is the main driver of this growth.

Purpose of the Study:

  • To evaluate the impact of integrated PET/CT on diagnostic performance and observer confidence.
  • To explore the future potential of PET/CT with novel radiopharmaceuticals and in bone imaging.

Main Methods:

  • Review of existing literature on FDG-PET/CT performance.
  • Comparison of integrated PET/CT with standalone PET, standalone CT, and visually correlated PET-CT.

Main Results:

  • Integrated PET/CT demonstrates improved observer confidence and diagnostic performance over individual modalities.
