Long-term effects of radioiodine treatment on thyroid functions and ultrasonographic features in patients with toxic adenoma and toxic multinodular goitre

ConclusionsThe volume of thyroid gland and toxic nodules continuously decreases, as the risk of hypothyroidism increases up to 10  years after RAI treatment. After RAI treatment, patients should be followed up to check their thyroid functions. In post-RAI examinations, toxic nodules may show ultrasonographic features suspicious for malignancy. History taking should include previous RAI therapies and old scintigraphy scans sho uld be evaluated to avoid unnecessary procedures and non-diagnostic biopsy results.
