Usefulness of Magnetic Resonance Sialography for the Evaluation of Radioactive Iodine-Induced Sialadenitis.

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.
