Lung Cancer Screening CT Report Generator
Structured reporting with Lung-RADS v2022 · Multi-nodule · S modifier · PACS-ready output
Pre-assessment
Select if the study is incomplete (Cat 0) or if there are no nodules / only benign findings (Cat 1). Otherwise, leave as "None" to proceed to nodule assessment.
Nodule Assessment
Nodules
Select nodule type to begin.
Auto-generated from findings
LOW-DOSE CHEST CT — LUNG CANCER SCREENING COMPARISON: None available. FINDINGS: Pulmonary Nodules: 1. Nodule 1 (Not specified): baseline scan. Mediastinum: No significant mediastinal or hilar lymphadenopathy. IMPRESSION: No significant findings. Continue annual screening with LDCT.
Lung-RADS v2022 — assessment categories
Malignancy likelihood and management by ACR Lung-RADS v2022 category. Management strings mirror this calculator's output.
| Category | Malignancy likelihood | Typical management |
|---|---|---|
| Lung-RADS 0 | n/a (incomplete) | Additional imaging or comparison needed (prior CT for comparison or complete lung imaging). |
| Lung-RADS 1 | <1% | Continue annual screening with LDCT (LDCT in 12 months). |
| Lung-RADS 2 | <1% | Continue annual screening with LDCT (LDCT in 12 months). |
| Lung-RADS 3 | 1–2% | LDCT in 6 months. |
| Lung-RADS 4A | 5–15% | LDCT in 3 months; PET/CT may be used. |
| Lung-RADS 4B | >15% | Tissue sampling, PET/CT, or both; management as clinically indicated. |
| Lung-RADS 4X | >15% | Tissue sampling and/or PET/CT, with additional workup as indicated. |
Key decision rules (v2022)
- Nodule type (solid, part-solid, or ground-glass [GGN]) is the first branch point; for part-solid nodules the solid-component size, not the total size, drives the category.
- Solid nodules: <6 mm is category 1, 6 to <8 mm is category 3, 8 to <15 mm is category 4A, and ≥15 mm is category 4B (baseline or new).
- Part-solid nodules: a solid component <4 mm scores category 2–3, 4 to <6 mm scores category 4A, and ≥6 mm scores category 4B (baseline or new).
- Ground-glass nodules: <30 mm is category 2 at baseline (or 3 if new); ≥30 mm is category 3.
- New vs stable vs growing changes the threshold: a stable nodule ≥12 months is downgraded toward category 2, while a growing nodule is upgraded (e.g. a solid nodule growing to ≥8 mm becomes category 4B).
- The S modifier flags a clinically significant or potentially significant non-Lung-RADS finding (e.g. spiculation, lymphadenopathy, direct invasion, pleural effusion); when any suspicious feature is present the assessment is escalated to category 4X.
- Category 0 is assigned when prior CT is unavailable for comparison or the lungs are not fully imaged; category 1 also covers a completely calcified nodule or a fat-density (hamartoma) nodule.
