1. Crystal Type & Sensitivity
Crystal material determines image quality and scan efficiency.
- LYSO/LSO: best timing resolution for TOF PET
- BGO: high stopping power, no TOF capability
- TOF PET significantly improves image quality

Buyer's Guide
Buying a Pre-Owned PET/CT System: Key Considerations
PET/CT is the primary staging and response-assessment tool for oncology. This guide covers the key technical and infrastructure factors for a successful pre-owned PET/CT acquisition.
2. Time-of-Flight Capability
TOF localises the annihilation event for sharper images.
- Confirm timing resolution (ps)
- Critical for larger patient populations
- Available in most mid-to-late generation systems
3. Axial Field of View
Larger AFOV means fewer bed positions and faster whole-body scans.
- Standard AFOV: 15–26 cm
- Larger AFOV reduces total scan time meaningfully
- Impacts patient dose and throughput
4. Integrated CT Performance
CT quality affects attenuation correction and diagnostic capability.
- 16, 40, or 64-slice integrated CT options
- Independent CT image quality testing
- Confirm software version and available options
5. Brands We Supply

- Export and import radiation licensing
- Destination-country regulatory approvals
Common Questions
Common Buyer Questions
Answers to the most common questions about pre-owned PET/CT systems.
What is the difference between LSO/LYSO and BGO detectors in clinical PET?
LYSO/LSO crystals offer higher light output, faster decay time, and better timing resolution than BGO, enabling time-of-flight imaging and faster acquisitions. BGO detectors have higher stopping power (sensitivity) but are slower. Modern systems use LYSO or LGSO for the best combination of sensitivity and TOF performance. BGO systems remain clinically functional for non-TOF FDG oncology applications at lower acquisition cost.
Do I need a local cyclotron to operate a PET/CT?
No. FDG (the most commonly used PET radiopharmaceutical) is produced by regional cyclotron facilities and distributed to hospitals within a 2–3 hour radius due to the 110-minute half-life of F-18. Many hospitals receive daily FDG deliveries from regional production centres. Verify the delivery schedule and lead times from your nearest supplier before committing to a PET programme.
What regulatory approvals are needed to import and operate PET/CT?
Requirements vary by country but typically include: export licence from origin country (for radioactive source-capable equipment), import customs clearance, radiation safety authority approval for the installation, site radiation survey, and a radioactive materials licence for isotope use. NOVO Imaging manages export licensing and can advise on destination-country regulatory requirements.
How important is axial field of view in clinical PET?
A larger axial FOV covers more body anatomy per bed position, reducing total scan time and patient dose. Standard AFOV (15–26 cm) typically requires 6–8 bed positions for a whole-body FDG scan (3–5 minutes per position). Larger AFOV systems (40–50 cm) reduce bed positions and total scan time meaningfully. Total-body PET (>100 cm AFOV) enables ultra-fast single-bed scans but are primarily research tools at present.
