The Neck Imaging Reporting and Data System (NI-RADS) is a practical and clinically useful imaging surveillance template designed to guide appropriate imaging follow-up and next-management steps. This article is a practical guide for using NI-RADS to reduce report-generation time for radiologists and create useful reports for referring clinicians and patients. A review of the report template and legend is followed by a case-based and pictorial review of the proper assignment of NI-RADS categories.
