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 | 1 — No evidence of recurrence |
→ManagementRoutine surveillance
- Site/category：Primary site · NI-RADS 1: No evidence of recurrence (~4%)
- 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
| Site assessed | Cervical nodes |
|---|---|
| NI-RADS category | 4 — Known/proven recurrence |
→ManagementMultidisciplinary management
- Site/category：Cervical nodes · NI-RADS 4: Known / biopsy-proven recurrence
- Management：Proven recurrence: multidisciplinary management for recurrence (definitive treatment)
- 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
Common questions
What is Head & Neck NI-RADS (Post-treatment Surveillance)?
Get the recurrence suspicion and management for post-treatment head-and-neck cancer surveillance imaging by site and NI-RADS category. Instant, browser-side.
How is Head & Neck NI-RADS (Post-treatment Surveillance) calculated? What is the core formula?
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.
When is Head & Neck NI-RADS (Post-treatment Surveillance) used?
Interpret a NI-RADS category at the primary site or neck during post-treatment surveillance.
What are the key clinical points for Head & Neck NI-RADS (Post-treatment Surveillance)?
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.
What are the limits and cautions when using Head & Neck NI-RADS (Post-treatment Surveillance)?
For licensed clinicians and clinical researchers. Interpret results with history, investigations and local protocols; not a diagnosis or prescription, and not a substitute for multidisciplinary decision-making or local guidelines.
