Core Tip
Core Tip: Although several guidelines on managing specific incidental findings (IFs) already exist and largely enable clinical practice, standardized recommendations accommodated within written radiology reports are lacking. We propose the use of the Incidental Reporting and Data System (I-RADS) to promote clarifying the necessity of next steps and management of IFs within radiology reports, similar to other “Reporting and Data System” systems. I-RADS attempts to improve communication among physicians and standardize recommendations while also allowing the promotion of research. Along with preexisting tools and guidelines, adoption of I-RADS could harmonize IFs management, diminish misunderstandings, improve patient outcomes, and support multicenter studies.
