NoduleRisk vs ILD Patterns

NoduleRisk is a clinical decision support tool for physicians evaluating pulmonary nodule malignancy risk. It computes probability estimates and management guidance across five validated models simultaneously. MODELS INCLUDED • Mayo Clinic (ACCP) — logistic regression model for incidentally detected nodules • Brock (BTS/PanCan) — recommended for screening populations; validated in the Pan-Canadian Lung Cancer Screening Study • Herder (BTS) — incorporates FDG-PET/CT uptake when available • BIMC (Bayesian) — Bayesian likelihood ratio model with adjustable prior probability; displays individual likelihood ratio contributions • Fleischner 2017 — guideline-based follow-up recommendations with automatic risk stratification FEATURES • Multi-nodule evaluation (up to 6 nodules per patient) • Volume doubling time calculation from serial CT measurements • Risk-stratified management recommendations for each model • Applicability warnings when inputs are outside model validation ranges • Clinical context adjustments for screening and biopsy-referred populations • Fully offline — no data is transmitted or stored IMPORTANT NoduleRisk is intended for use by qualified clinicians as a decision support aid only. Results must be interpreted in the context of the full clinical picture and do not substitute for institutional guidelines, multidisciplinary team discussion, or clinical judgment.

ILD Patterns puts the 2025 ERS/ATS interstitial pneumonia classification in your pocket — built for pulmonologists, pulmonary fellows, residents, radiology trainees, and medical students who want fast, structured HRCT morphology study without digging through PDF tables. Use the pattern analysis tool or the Pattern listing descriptions on-the-go. Medical education and 2025 guideline-based educational referencing. EDUCATIONAL USE ONLY — NOT FOR PATIENT DIAGNOSIS This app is for professional education and self-study. It is NOT medical advice, NOT software as a medical device (SaMD), NOT clinical decision support, and NOT intended for patients. Outputs are educational morphology suggestions only. PATTERN TOOL — EDUCATIONAL RANKING ENGINE • Select HRCT imaging features across six ABCDEF groups (distribution, density, signs, and more) • Generate an educational ranked morphology differential across major interstitial patterns and rare alveolar-filling patterns (Table 2 + Supplementary Table S2) • Tap any result for a detail sheet: supporting features, features arguing against, Table 1 associated diagnoses, pathology excerpts, and Table 4 combined-pattern references • Review educational fit badges, conflict cautions, combined morphology notes, and an anchor eligibility checklist • Ideal for fellows learning systematic ILD review, residents on pulmonary rotations, and attendings teaching pattern recognition PATTERN LIST — FULL GUIDELINE REFERENCE LIBRARY • Browse verbatim ERS/ATS 2025 tables: UIP, NSIP, BIP, DAD, PPFE, LIP, organising pneumonia, RB-ILD, AMP, and rare alveolar-filling patterns (PAP, eosinophilic pneumonia, lipoid pneumonia) • Clinical, radiological, and pathological columns plus Table 1 secondary and primary diagnoses • Table 3 organising pneumonia subpatterns (OP, AFOP, CiOP) • Table 4 combined radiological-histological patterns with common differential diagnoses • Free tier includes a sample of entries; Premium unlocks all 22 expandable reference cards WHO IT'S FOR • Pulmonologists and pulmonary fellows building fluency with the 2025 classification • Internal medicine and pulmonary residents on ILD rotations • Medical students learning HRCT morphology vocabulary • Radiology trainees aligning pattern language to ERS/ATS tables • Educators preparing teaching sessions, M&M discussions, or board-style review FREE & PREMIUM FREE INCLUDES: • 5 educational pattern interpretations (Pattern Tool) • Sample Pattern List entries to explore the guideline library ILD PATTERNS PREMIUM: • Unlimited educational pattern rankings • Full Pattern List — every morphology entry, OP subpattern, and combined-pattern group • Restore purchases on the same Apple ID PRIVACY BY DESIGN • No logins • Rankings stay on your device; developer does not collect feature selections or analytics GUIDELINE SOURCE Ryerson CJ, Walsh SLF, Sverzellati N, et al.

IMPORTANT LIMITATIONS Outputs are educational morphology suggestions based only on user-selected imaging features. They may be incomplete or incorrect. Educational rankings do not replace multidisciplinary discussion, radiology or pathology review, institutional protocols, or independent clinical judgement. Numeric scores are an educational approximation of qualitative guideline language and have not been validated against patient cohorts. Fit badges reflect educational morphology alignment — not ERS/ATS multidisciplinary diagnostic confidence percentages. SUBSCRIPTION TERMS Payment charged to your Apple ID at confirmation.
