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.

SettingIncidental (Fleischner, age ≥35)
Locationright upper lobe
Image number (optional)128
DensitySolid
Long axis9 mm
Short axis (perpendicular, same slice)7 mm
MarginSmooth
CalcificationNone
Pleural retractionNo
Bubble lucency / air bronchogramNo
ComparisonFirst seen / no prior
NumberSingle
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
SettingLDCT screening baseline (Lung-RADS)
Locationleft lower lobe
Image number (optional)128
DensityPure ground-glass
Long axis9 mm
Short axis (perpendicular, same slice)7 mm
MarginSpiculated
CalcificationEccentric / stippled (non-benign)
Pleural retractionYes
Bubble lucency / air bronchogramYes
ComparisonNew
NumberMultiple (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.

Common questions

What is Lung Nodule Structured Report (with Fleischner / Lung-RADS follow-up)?

Point-and-click features generate standardized lung nodule findings, impression and follow-up (Fleischner 2017 incidental, Lung-RADS v2022 screening) ready to paste. Instant, browser-side.

How is Lung Nodule Structured Report (with Fleischner / Lung-RADS follow-up) calculated? What is the core formula?

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).

When is Lung Nodule Structured Report (with Fleischner / Lung-RADS follow-up) used?

Chest CT reporting, resident training and terminology QA.

What are the key clinical points for Lung Nodule Structured Report (with Fleischner / Lung-RADS follow-up)?

Mean of long and short axis. Incidental → Fleischner. Screening → Lung-RADS. Growing nodules assessed separately.

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?
