The expression of diagnostic certainty in radiology reports is common and used to inform clinicians and patients about the degree of confidence a radiologist has in a finding or differential diagnosis. However, radiologists express diagnostic certainty in myriad ways, which leads to ambiguity and risk of misdirected clinical management. Standardizing how diagnostic certainty is expressed is likely to improve the fidelity of information transfer between radiologists and referring providers and pa…

ACR Neck Imaging Reporting and Data System (NI-RADS) for Magnetic Resonance Imaging v2025
Post-treatment surveillance imaging of head and neck cancers poses substantial interpretation challenges, due to the anatomic complexities of the region and to the changes from surgical resection, reconstruction, radiation therapy, and chemotherapy. As a result, there is frequent variability in how individual radiologists report the same imaging findings and in the levels of suspicion for recurrence with which different radiologists view identical imaging findings. In response, the American Coll…
