Question

Thyroid ultrasound is recommended for managing thyroid nodules and can aid in visualization of the nodule for biopsy (fine needle aspiration [FNA]), which is necessary to help distinguish benign from malignant etiology. Magnetic resonance imaging is the preferred choice for pituitary and hypothalamic imaging. Isotopic imaging includes radioactive scanning of the thyroid (e.g., using radioiodine), parathyroids (e.g., using sestamibi), and adrenals (e.g., using metaiodobenzylguanidine [MIBG] to detect pheochromocytoma).
