Area of Science:

  • Radiology
  • Medical Imaging
  • Oncology

Background:

  • Combined positron emission tomography/computed tomography (PET/CT) is crucial in oncology.
  • Current clinical practice uses varied CT imaging protocols within PET/CT acquisition.
  • Maximizing PET/CT's oncologic potential requires leveraging the full capabilities of CT.

Purpose of the Study:

  • To review radiological perspectives on optimizing CT protocols for combined PET/CT imaging.
  • To highlight the importance of diagnostic-quality CT within PET/CT for oncology.
  • To address challenges and considerations for integrating full CT protocols into PET/CT.

Main Methods:

  • Review of radiological best practices for CT acquisition in PET/CT.
  • Discussion of requirements for diagnostic CT, including contrast administration.

  • Consideration of CT image quality standards and potential artifacts in PET/CT.

    • Main Results:

    • Full utilization of CT's diagnostic capacity in PET/CT requires specific protocol adjustments.
    • Oral and intravenous contrast agents are necessary for comprehensive oncologic assessment.
    • Attention must be paid to potential PET/CT artifacts arising from CT attenuation correction.

    Conclusions:

    • Integrating fully diagnostic CT protocols into PET/CT is essential for advanced oncology imaging.
    • Radiological standards for CT quality must be met to ensure diagnostic sufficiency.
    • Careful protocol design is needed to balance CT diagnostic needs with PET/CT artifact mitigation.
