Lymphoma Staging & Response PET/CT
18F-FDG≈ 15 min on the scanner
In simple words
Lymphoma is one of the cancers PET changed the most. Chemotherapy can shrink a lymph node while live disease persists inside it, and it can leave a lump of harmless scar tissue behind after a cure. PET tells the two apart by showing whether anything in that lump is still metabolically alive.
Questions this scan answers
- What stage is the lymphoma?
- Is the chemotherapy working after 2 cycles, or should the regimen change?
- Is there any active disease left at the end of treatment?
The Prismaa difference
We report every lymphoma study with a Deauville 5-point score against the mediastinal blood pool and liver reference — the exact language haematologists use to decide whether to escalate or de-escalate treatment.
Usually recommended for
- Hodgkin and non-Hodgkin lymphoma at diagnosis
- Interim response assessment (typically after 2 cycles)
- End-of-treatment assessment and surveillance
How to prepare
- Fast for 6 hours; water is fine.
- Avoid exertion for 24 hours before the scan.
- Ideally scan at least 10 days after your last chemotherapy cycle, and 2 weeks after G-CSF injections, unless your doctor says otherwise.
