Molecular Imaging Advances in Thyroid Cancer

Thyroid cancer is relatively uncommon compared to other malignancies but its incidence is increasing. This article reviews the clinical aspects of evaluating a thyroid nodule and the role of various imaging modalities. Ultrasound and fine needle aspiration biopsy are the mainstays for initial evaluation. Radioiodine scintigraphy helps characterize nodules that are indeterminate on cytology. PET/CT with FDG is particularly useful for more aggressive histologies and radioiodine negative disease. The improved sensitivity and specificity of PET/CT continues to expand its utility in this disease.
