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

MRI NI-RADS showed moderate inter-rater agreement in OPSCC patients, with greater interpretative challenges in the evaluation of the first post-treatment MRI. Regular application of the NI-RADS in clinical settings may help enhance consistency and reliability in imaging evaluations.
