Read full description

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 β€’ Mayo Clinic (ACCP) β€” logistic regression model for incidentally detected nodules β€’ Brock (BTS/PanCan) β€” recommended for screening populations; validated in the Pan-Canadian Lung Cancer Screening Study β€’ Herder (BTS) β€” incorporates FDG-PET/CT uptake when available β€’ BIMC (Bayesian) β€” Bayesian likelihood ratio model with adjustable prior probability; displays individual likelihood ratio contributions β€’ Fleischner 2017 β€” guideline-based follow-up recommendations with automatic risk stratification FEATURES β€’ Multi-nodule evaluation (up to 6 nodules per patient) β€’ Volume doubling time calculation from serial CT measurements β€’ Risk-stratified management recommendations for each model β€’ Applicability warnings when inputs are outside model validation ranges β€’ Clinical context adjustments for screening and biopsy-referred populations β€’ Fully offline β€” 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.

About

PFT Spirometry

Features
Read full description

Make sense of pulmonary function testsβ€”one pattern at a time. PFT Spirometry helps clinicians and medical learners practise PFT interpretation, compare the 2022 and 2005 ERS/ATS frameworks, and build clear reports for teaching and study. FROM VALUES TO A CLEAR PATTERN Enter spirometry, lung volumes, gas-transfer and bronchodilator measurements. Start with the pattern, then review relevant parameters, applicable severity grading and important gaps in the supplied data. Explore obstruction, restriction, mixed patterns and preserved-ratio abnormalities in one focused workspace. TWO FRAMEWORKS, ONE LEARNING TOOL Use PFTs 2022 for the 2022 interpretive framework or PFTs 2005 for the earlier strategy. Compare approaches while studying lung function, reviewing older reports or preparing for pulmonary medicine teaching and examinations. Enter the reference values supplied by the source laboratory. LESS TYPING WITH PHOTO IMPORT (BETA) Scan a report with the camera, choose a photo or open a PDF page. Native on-device recognition suggests values for review. Crop or rotate the table, compare suggestions with the source, correct entries and apply reviewed values before tapping Interpret. Recognition varies with image quality and layout; it may omit or misread values. Visual verification is required. REPORTS THAT KEEP THE DETAILS TOGETHER Create one-page PDF reports with raw values as entered, findings, the pattern summary, notes and educational limitations. Save, label, search and revisit reports for learning. Copy results or share a PDF using your device's sharing options. Use de-identified teaching cases. A SEARCHABLE PFT REFERENCE Open focused, collapsible Notes topics covering reference limits, spirometry quality, ventilatory patterns, bronchodilator response, lung volumes, DLCO, VA/KCO and interpretation pitfalls. Clinical context and differential considerations stay in Notes, separate from the tools' algorithmic pattern output. Follow linked primary references for further reading. MADE FOR FOCUSED STUDY A compact interface, optional slider inputs and adjustable text size help you work at your preferred pace on iPhone or iPad. Interpretation and report storage run locally; no app account is required. Imported images are not attached to saved reports or uploaded to a developer-operated recognition service. FREE AND PREMIUM Free access includes most Notes topics, reading preferences, educational-use information and previews of the tools. PFT Premium unlocks both interpretation tools, photo import (Beta), PDF export, saved report history and all Notes topics. Monthly and yearly auto-renewing plans are available. Prices and any eligible introductory trial are shown before purchase. EDUCATIONAL USE For qualified healthcare professionals and medical learners under appropriate supervision. Outputs are algorithmic educational pattern suggestions, not diagnoses or treatment advice. They may be incomplete or incorrect and require independent verification by a qualified clinician against the original report, test quality, clinical context and applicable standards. Not for patient self-diagnosis or use as the sole basis for clinical decisions. SUBSCRIPTIONS Payment is charged to your Apple Account. Subscriptions renew automatically unless cancelled at least 24 hours before the current period ends. Any eligible trial renews at the displayed subscription price unless cancelled.
