Inter-rater reliability of MRI Neck Imaging Reporting and Data System (NI-RADS) in the follow-up of oropharyngeal squamous cell carcinoma

Key Points

• To assess the inter-rater reliability of MRI NI-RADS in follow-up imaging for oropharyngeal squamous cell carcinoma (OPSCC).
• Evaluated MRI imaging using NI-RADS for OPSCC patients.
• Assessed inter-rater agreement among multiple radiologists.
• Focused on the first post-treatment MRI for reliability analysis.
• Demonstrated moderate inter-rater agreement in interpreting MRI NI-RADS.
• Identified greater challenges in evaluating the first post-treatment MRI.
