Novel detector technology for clinical PET.

Area of Science:

• Medical Imaging
• Molecular Imaging
• Radiochemistry

Background:

• Positron emission tomography (PET) offers unparalleled molecular sensitivity.
• PET's spatial resolution is limited compared to anatomical imaging (CT, MR).

Purpose of the Study:

• To integrate PET with complementary anatomical imaging modalities.
• To enhance PET's utility in pre-clinical and clinical research.
• To explore synergistic benefits of combined imaging.

Main Methods:

• Sequential acquisition using current PET/CT technology.
• Development of novel integrated PET/MR and PET/CT systems for concurrent imaging.

Main Results:

• Sequential PET/CT enables combined molecular and anatomical data acquisition.
• Emerging integrated systems aim for simultaneous dual-modality imaging.

Conclusions:

• Integrated PET/CT and PET/MR systems are under development.
• These novel instruments present significant challenges for PET detection systems.
• Future PET detectors must meet stringent requirements beyond standard PET imaging.
