Summary
High-performance PET and SPECT scanners are crucial for preclinical drug development, offering superior resolution and sensitivity. This review highlights innovative animal imaging systems and their applications.
Area of Science:
- Nuclear medicine
- Medical imaging
- Pharmacology
Background:
- Growing interest in Positron Emission Tomography (PET) and Single-Photon Emission Computed Tomography (SPECT) for drug development.
- Preclinical studies necessitate dedicated small animal scanners with enhanced spatial resolution and sensitivity compared to clinical systems.
Purpose of the Study:
- To review potential applications of innovative PET and SPECT instruments in drug development.
- To provide an overview of dedicated PET and SPECT tomographs developed globally.
- To describe the technical characteristics and performance of the YAP-(S) PET scanner.
Main Methods:
- Review of existing dedicated PET and SPECT tomographs worldwide.
- Description of the YAP-(S) PET scanner developed at the University of Ferrara.
- Discussion of emerging combined imaging techniques (PET/CT, SPECT/CT).
Main Results:
- Most dedicated animal scanners are research prototypes; only micro-PET and HIDAC PET are commercially available.
- The YAP-(S) PET scanner offers high performance for both PET and SPECT studies.
- Combined PET/CT and SPECT/CT systems are under development, promising advanced imaging capabilities.
Conclusions:
- Dedicated PET and SPECT scanners are vital for advancing small animal imaging in drug discovery.
- Innovative tomographs, like the YAP-(S) PET, enhance research capabilities.
- Future developments in combined imaging modalities will further benefit preclinical research.
