Lung nodules are frequently discovered on CT imaging - either incidentally or during low-dose lung cancer screening.

Choosing the appropriate CT follow-up interval in these situations can be challenging due to the intricate and dynamic nature of the Fleischner Society and American College of Radiology Lung-RADS guidelines.

The most current versions of these guidelines for managing incidentally discovered lung nodules and lung nodules discovered during lung screening are elegantly integrated in this app, in addition to a convenient tool to estimate the malignancy risk for any lung nodule.

This app was developed as a public service by two academic cardiothoracic radiologists and recognized medical educators, and is provided free of charge and free of advertising to the medical community.
