Incidental Lung Nodule Guide vs NoduleRisk

Download includes a free trial; continued use requires a 6- or 12-month auto-renewing subscription. Incidental Lung Nodule Guide is a decision-support guide that helps radiologists, pulmonologists, and primary-care clinicians apply the 2017 Fleischner Society guidelines for incidental pulmonary nodules on CT in their daily workflow. The app offers a streamlined, intuitive interface that supports consistent and informed decision-making at the point of care. Key Features (unlocked after free trial with an active subscription): Guideline-Based Support • Structured recommendations for both solid and subsolid (non-solid and part-solid) nodules—based on nodule size, nodule attenuation, whether solitary or multiple, and patient-specific risk factors. Interactive Visual Timeline • Follow-up intervals are clearly visualized, showing recommended CT timeframes based on the selected inputs—making guideline application fast and easy. Visual Aids • Illustrative examples help with identifying nodule calcification patterns and nodule density. Comprehensive Nodule Insights • Includes guidance on perifissural nodules, apical scarring, and nodules incidentally found on neck or abdominal CT scans. Self-Assessment Mode • Expert-curated self-assessment questions. Brock (Full Model) Calculator • Calculate a CT-detected nodule’s 2–4 year malignancy risk. Enhanced Readability • Designed for daily clinical use with support for dark mode and dynamic text sizing—helping ensure legibility in diverse reading environments. Offline Access • No login or server needed. Medical Disclaimer: This app is for informational purposes only and is not a substitute for professional medical advice. In addition to using this app, always consult a qualified healthcare provider for diagnosis and treatment decisions.

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.
