Methodology · worked example, guidelines & full notes
Primary site and neck are scored 1–4 separately.
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.

Worked calculation
The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.
| Site assessed | Primary site |
|---|---|
| NI-RADS category | 2b — Low suspicion (deep) |
→ManagementShort follow-up ± PET
- Site/category：Primary site · NI-RADS 2b: Low suspicion · deep
- Management：Deep suspicion at primary: short-interval follow-up imaging (~3 mo) ± PET/CT
- Note：NI-RADS is for post-treatment surveillance of head-and-neck SCC (CECT/MRI ± PET); primary and neck are scored 1–4 separately; PET mainly evaluates primary 2b and neck category 2; higher categories carry higher recurrence probability
| Site assessed | Primary site |
|---|---|
| NI-RADS category | 1 — No evidence of recurrence |
→ManagementRoutine surveillance
- Site/category：Primary site · NI-RADS 1: No evidence of recurrence
- Management：Routine surveillance imaging (at the set interval)
- Note：NI-RADS is for post-treatment surveillance of head-and-neck SCC (CECT/MRI ± PET); primary and neck are scored 1–4 separately; PET mainly evaluates primary 2b and neck category 2; higher categories carry higher recurrence probability
