The key features of this app are the Brock and Herder risk prediction and volume doubling time (VDT) calculators that are recommended by British Thoracic Society (BTS) to assist in the diagnosis and management of pulmonary nodules. In the calculators we’ve included associated recommendations from the BTS on patient management. This app has been produced by Cancer Research UK in collaboration with BTS to give clinicians quick and easy access to the calculators and the BTS guidelines for the investigation and management of pulmonary nodules. It includes the four management algorithms that appear in the full guideline document and summarise key parts of the guidelines. These calculators and management algorithms should be used in conjunction with the full BTS Guidelines published in 2015 (Thorax 70, Supplement 2). This app is designed as a tool for clinicians. If you are a patient concerned about your lung health or scan results, you should speak to your doctor or GP. You can also have a look at Cancer Research UK’s patient information website and talk to our cancer information nurses online or by phone. ## Key features - Brock risk prediction calculator - Herder risk prediction calculator - Volume Doubling Time (VDT) calculator - BTS patient management recommendations - Management algorithms summary - Quick access to guidelines ## Recent user reviews (3 of 3) All indexed reviews: https://appshunter.io/ios/app/pulmonary-nodule-risk/id1142255949/reviews.md ### 3/5 — Needs updating for iOS 14? *2020-09-22* I usually find this a really help app for me and for patients, to quantify risk of nodules.

Minor bug fixes. ### 2.0.1 — 2017-10-05 What’s New in Version 2.0 The following updates have been made based on user feedback: The Herder & Brock calculators now display only the recommendations that are relevant to the predicted risk, based on patient and nodule details. The VDT calculator now displays only recommendations that are relevant to the measurement method selected (volume/diameter) and the predicted VDT, based on nodule details. The VDT calculator now highlights when a nodule is considered stable according to the BTS guidelines, and displays only the recommendations that are relevant to stable nodules. The nodule management guidelines and calculators are linked to each other at the relevant steps, making it quicker and easier to switch between them. The algorithms and calculators have been redesigned to make them more elegant. ### 2.0 — 2017-10-03 What’s New in Version 2.0 The following updates have been made based on user feedback: The Herder & Brock calculators now display only the recommendations that are relevant to the predicted risk, based on patient and nodule details.
