Positron emission tomography/computed tomography (PET/CT) integrates functional and anatomical imaging for cancer staging. This combined approach offers faster scans, precise tumor localization, and efficient single-step staging, improving patient care.

Area of Science:

  • Nuclear Medicine
  • Radiology
  • Oncology

Background:

  • 18F-fluorodeoxyglucose (FDG) Positron Emission Tomography (PET) is crucial for cancer staging and follow-up.
  • PET imaging relies on tracer distribution, necessitating anatomical correlation for accurate interpretation.
  • Integrated PET/CT scanners provide simultaneous functional and anatomical data, enhancing diagnostic capabilities.

Purpose of the Study:

  • To review the technical characteristics of state-of-the-art PET/CT systems.
  • To provide an overview of PET/CT acquisition protocols.
  • To describe the clinical applications of PET/CT in oncology.

Main Methods:

  • Review of technical specifications for three advanced PET/CT systems.
  • Description of standardized PET/CT acquisition protocols.

  • Analysis of clinical utility and advantages of PET/CT in oncological imaging.

    • Main Results:

    • Integrated PET/CT systems offer direct fusion of PET and CT data in a single session.
    • CT imaging aids in PET data attenuation correction.
    • PET/CT demonstrates advantages including shorter acquisition times, improved anatomical localization of tumors, and single-step disease staging.

    Conclusions:

    • PET/CT enhances diagnostic accuracy and efficiency in oncology compared to PET alone.
    • The integration of PET and CT imaging streamlines patient throughput and improves diagnostic confidence.
    • PET/CT represents a significant advancement in oncological imaging, influencing routine clinical practice.
