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.
| Lower edge from anal verge | 6 cm |
|---|---|
| Tumor length | 4 cm |
| Circumferential extent | 1/4–1/2 |
| T stage | T3 (beyond muscularis; a–d by depth) |
| T3 extramural depth (beyond muscularis) | 4 mm |
| Closest distance of tumor / node / deposit to MRF | 3 mm |
| EMVI | Negative |
| Suspicious mesorectal nodes (incl. tumor deposits) | 2 nodes |
| Lateral pelvic nodes | None suspicious |
| Mucinous content | None / <50% |
| Sphincter involvement (low tumors) | Internal sphincter |
→MRI stagemT3bN1
- Report block：Mid rectal cancer, lower edge 6 cm from the anal verge, length 4 cm, involving 1/4–1/2 of the circumference. Tumor extends beyond the muscularis propria by 4 mm (mT3b). Closest distance to the mesorectal fascia 3 mm, MRF clear. EMVI negative. 2 suspicious mesorectal node(s)/deposit(s) (mN1); no suspicious lateral pelvic nodes. Tumor involves the internal sphincter.
- High-risk features：None (MRF−, EMVI−, ≤T3b, N0–1, lateral−)
- Node criteria (ESGAR)：Short axis ≥9 mm; 5–8 mm with ≥2 morphologic criteria; <5 mm with all 3 (round, irregular border, heterogeneous signal); mucinous nodes suspicious at any size.
| Lower edge from anal verge | 6 cm |
|---|---|
| Tumor length | 4 cm |
| Circumferential extent | ≤ 1/4 |
| T stage | T1–2 (confined to wall) |
| T3 extramural depth (beyond muscularis) | 4 mm |
| Closest distance of tumor / node / deposit to MRF | 3 mm |
| EMVI | Negative |
| Suspicious mesorectal nodes (incl. tumor deposits) | 2 nodes |
| Lateral pelvic nodes | None suspicious |
| Mucinous content | None / <50% |
| Sphincter involvement (low tumors) | N/A / not involved |
→MRI stagemT1–2N1
- Report block：Mid rectal cancer, lower edge 6 cm from the anal verge, length 4 cm, involving ≤ 1/4 of the circumference. Tumor confined to the bowel wall (mT1–2). Closest distance to the mesorectal fascia 3 mm, MRF clear. EMVI negative. 2 suspicious mesorectal node(s)/deposit(s) (mN1); no suspicious lateral pelvic nodes.

What are the limits and cautions when using Rectal Cancer MRI Structured Report (T stage / MRF / EMVI / N)?
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.
Does Rectal Cancer MRI Structured Report (T stage / MRF / EMVI / N) upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
