Hyperthyroid/Graves

US is the best screening procedure to confirm the presence of thyroid nodule. It can determine whether the mass is cystic or solid. US can also facilitate biopsy of the mass. CT can also be used for detection and biopsy but is essential for staging. US is simple, can be done at bed side and involves no radiation.
