Head & Neck NI-RADS (Post-treatment Surveillance)
Site assessed
NI-RADS category
When to use
Interpret a NI-RADS category at the primary site or neck during post-treatment surveillance.
How it works
1 no recurrence → routine surveillance; 2a/2b low suspicion → clinical follow-up or short-interval imaging ± PET; 3 high suspicion → biopsy; 4 proven recurrence → multidisciplinary management.
Key points
- Primary site and neck are scored 1–4 separately.
- PET mainly evaluates primary 2b and neck category 2.
- Category 3 (new/enlarging soft tissue, bony erosion, nodal necrosis or ENE) warrants biopsy.
- Higher categories carry higher recurrence probability.
