Purpose Radioactive iodine (RAI) ablation therapy after thyroidectomy commonly leads to obstructive sialadenitis. Magnetic resonance (MR) sialography is an emerging imaging modality that enables morphological and functional changes to be evaluated. This study was conducted to investigate the usefulness of MR sialography for the evaluation of RAI sialadenitis. In addition, the authors evaluated the correlation of MR sialographic grading with symptom severity using a symptom questionnaire (SQ), and salivary gland (SG) functions as determined by salivary flow rates (SFRs) and salivary scintigraphy (SSG) parameters.
