Clinical takeaway
Mean of long and short axis.
When to use
Chest CT reporting, resident training and terminology QA.
How it works
Mean = (long + short)/2; Fleischner rounds to mm (solid <6, 6–8, >8; subsolid <6, ≥6); Lung-RADS keeps one decimal (solid <6/6–8/8–15/≥15).
Key points
- Mean of long and short axis.
- Incidental → Fleischner.
- Screening → Lung-RADS.
- Growing nodules assessed separately.

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.
| Setting | Incidental (Fleischner, age ≥35) |
|---|---|
| Location | right upper lobe |
| Image number (optional) | 128 |
| Density | Solid |
| Long axis | 9 mm |
| Short axis (perpendicular, same slice) | 7 mm |
| Margin | Smooth |
| Calcification | None |
| Pleural retraction | No |
| Bubble lucency / air bronchogram | No |
| Comparison | First seen / no prior |
| Number | Single |
| Lung cancer risk (incidental) | Low |
→Fleischner 2017 · mean diameter8mm
- Findings：A solid nodule in the right upper lobe (image 128), measuring 9 × 7 mm (mean 8 mm), with smooth margin, no calcification. First seen.
- Impression：solid nodule, right upper lobe, mean 8 mm
- Recommendation：CT at 6–12 months, then consider CT at 18–24 months
| Setting | LDCT screening baseline (Lung-RADS) |
|---|---|
| Location | left lower lobe |
| Image number (optional) | 128 |
| Density | Pure ground-glass |
| Long axis | 9 mm |
| Short axis (perpendicular, same slice) | 7 mm |
| Margin | Spiculated |
| Calcification | Eccentric / stippled (non-benign) |
| Pleural retraction | Yes |
| Bubble lucency / air bronchogram | Yes |
| Comparison | New |
| Number | Multiple (describe most suspicious) |
| Lung cancer risk (incidental) | High (smoking, family history, upper lobe, spiculation…) |
→Lung-RADS v20222
- Findings：Multiple nodules; the largest/most suspicious is a pure ground-glass nodule in the left lower lobe (image 128), measuring 9 × 7 mm (mean 8 mm), with spiculated margin, non-benign calcification, adjacent pleural retraction, bubble lucency / air bronchogram. New since prior.
- Impression：pure ground-glass nodule, Lung-RADS 2
- Recommendation：LDCT in 12 months. Note: baseline rules used; reassess new/growing nodules with the Lung-RADS tool.

FAQ
Frequently asked questions
- What are the limits and cautions when using Lung Nodule Structured Report (with Fleischner / Lung-RADS follow-up)?
- 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 Lung Nodule Structured Report (with Fleischner / Lung-RADS follow-up) 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.
- How is Lung Nodule Structured Report (with Fleischner / Lung-RADS follow-up) calculated in practice? Can you show a worked example?
